[Dsol-java] How can I clear the data set of a chart?

[Bennie T. <B.J...@st...>]

Hi all,

I have a XYChart and after certain time intervals, I would like to clear the
chart so that it starts drawing a new graph. Creating a new chart in place
of the old one does not help since the data of the old chart is then kept,
and it also creates a bunch of entries in the Statistics panel with the same
name. So actually I need to clear the dataset of the chart, but I couldn't
find a method that can wipe the slate clean.

Any ideas?

Thanks,
Bennie

thanks for your help!

Any thoughts on my second question about detecting low variances and cutting the 
simulation runs?

thanks!

[Houten, Stijn-P. v. <s.p...@tb...>]

Hi Mark,

Yes, it is very well possible to run dsol within a J2EE container. I
don't recall having problems with multiple threads and dsol in
combination with JBOSS. Of course, multiple ways exist to make a
simulator (or animator in this case) remotely available. Attached you
find three classes which together provide you with the idea of making an
animator remotely accessible, even without using JBOSS. However, you
could also let the classes that implement the SessionBean interface and
your EJBObject interface implement/extend the RemoteAnimatorInterface.
In the latter, you should make sure to delegate for example the
simulator.stop() method to the animator which is then an attribute of
the SessionBean.=20

Hope this helps, best regards,

Stijn-Pieter van Houten.

Onderwerp: [Dsol-java] simulator usage questions

Hi,

I'm looking to run your simulation software in a J2EE container,
specifically JBoss. I was wondering if anyone has any experience with
this before? The J2EE spec doesn't allow threads to be created on the
fly within the container, and by the looks of it, the simulations are
run multi-threaded. Am I correct in saying this or is it possible to
switch off thread spawning?

I'm also curious as to whether it is possible to detect if variations in
results reduce to a minimum. Take for instance the M/M/1 queue
simulation.=20
The d(n) chart approaches 0.717 after about 800,000 units, but after
that, there is no difference to these figures. Is it possible to
automatically detect this and stop the simulation going further?

thanks!

Mark

[Dsol-java] DSOL: New 3D animation tutorial

[R.T.H.Chin <r.t...@tb...>]

Hi all,

I wrote a 3D animation tutorial that is currently hosted at my personal 
website under the education-menu: 
http://www.tbm.tudelft.nl/webstaf/Royc/index.htm
Later on it may move to the official DSOL website.

Hope it's helpful,

[Bastiaan v. de R. <in...@ra...>]

Bennie,

That was exactly the problem. I didn't see the exact difference between 
the old and new versions of DSOL.
Now I on my way the specify my own specs of the animationframe.

Tnx a lot.

RE: [Dsol-java] Problems and question Animation Panel/Frame in DSOL

[Bennie T. <B.J...@st...>]

Bastiaan,

I think this problem is due to a change in the DSOLApplication() code. I
recently changed the libraries for a project from dsol-gui 1.6.2 to dsol-gui
1.6.4 and it resulted in the same error as you mentioned, while it worked
with the older library. On the DSOL website, the code for the latest version
(dsol-giu 1.6.6) shows the following for the DSOLApplication() constructor:

	/***
57  	 * constructs a new DSOLApplicationInterface
58  	 *
59  	 * @param navigation an URL to an xml-based navigation structure.
60  	 */
61  	public DSOLApplication(final URL navigation)

So, the argument "navigation" is added in the newer versions. The default
menu navigation structure is included in the jar file, so by adding a
parameter when calling DSOLApplication(), the problem should be solved:

	public BargeHandlingApplication()
    {
        super(URLResource.getResource("/navigation.xml");
        this.properties.put("dsol-gui.animation.panel.size","1020;680");
    }

Of course, if all else fails you can just use the older jar files.

Bennie

[Dsol-java] Animation of a DirectionalLine

[Loek <lo...@tb...>]

Hello everyone,

I want to display a line in my animation. Therefore I use a DirectionalLine
between 2 coordinates, (x1, y1) and (x2, y2). These input-values are
doubles, for example (4.0, -5.0) and.(8.0, 5.0). I got these values from an
object that has two Point3d-attributes.
Now I've the problem that when I animate these lines, they aren't
represented at the right coordinates at all. But when I multiply the
coordinates with a big number, for example 1000, the representation is much
better.
Does anyone know how is this possible? May this be a bug in the animation?

[Dsol-java] problem encountered: resource is granted before it is released by others

[Wei J. <j....@st...>]

Hi All,

I encountered a problem concerning resource. In my Dining Philosopher =
model, I have ChopStick Class defined as follows:

public class ChopStick extends Resource
in the constructor,=20
super(simulator, "chopstick(" + i + ")", 1.0);
So I defined ChopStick as resource of capacity 1.0

Then in Philosopher Class, it get the chopstick and requests the =
resource as follows:
getChopStick(LEFT_CHOPSTICK).requestCapacity(1.0, this);
getChopStick() returns an object of ChopStick class, so here the =
philosopher got his left chopstick and request it. After he finishes =
eating, he will release this chopstick, for =
examplegetChopStick(LEFT_CHOPSTICK).requestCapacity(1.0, this);

Other philosophers can also request the same chopstick. But as the =
capacity is only 1.0, once it is already granted to a philosopher, =
others' requests will be suspended until that philosopher release that =
resource.

However, in my program, I found the resource was granted before it was =
released.=20

For example, Philosopher(0) and Philosohper(4) are sitting next to each =
other, and chopstick(4) is between them. After running my program, I =
have the following output:
I, philosopher(0) got hungry

..

I, philosopher(4) got hungry

I, philosopher(4) got chopstick(4)

..

I, philosopher(0) got suspended on chopstick(4)

..

I, philosopher(0) got chopstick(4)

I, philosopher(0) am eating

chopstick(4) is released by philosopher(4)



In the begining it was correct, after philosopher(4) got chopstick(4), =
when Philosopher(0) requested chopstick(4), he couldn't get it so =
suspended on it; then later at another try phislopher(0) got it before =
chopstick(4) was actually released.=20

The code in this part is very simple, I can't find out why this =
happened.=20



Is there anything wrong with the way I request and release resource? If =
anyone of you are kind enough to help me solve it, you can refer to my =
source code, it is Comparison4 on CVS repository.

RE: [Dsol-java] Problems and question Animation Panel/Frame in DSOL

[Bennie T. <B.J...@st...>]

Define your own application by just extending the DSOLApplication (and
adding your new properties). Now just run this class instead of the
DSOLApplication class. For example:


import nl.tudelft.simulation.dsol.gui.DSOLApplication;

public class MyOwnApplication extends DSOLApplication
{
    public MyOwnApplication ()
    {
        super();

this.properties.put("dsol-gui.animation.panel.extent","10000;30000;10000;100
00");
        this.properties.put("dsol-gui.animation.panel.size","1020;680");
    }

    public static void main(String[] args)
    {
        new MyOwnApplication();
    }
}

First of all, thanks for your help.

I understand that the animation window are properties of the
DSOLApplication.

But where in my model can  I put such a constructor?  I don't define my
own Application, I just use the DSOLApplication  and load my model on
it. Can I define my own Application and run that?

RE: [Dsol-java] Problems and question Animation Panel/Frame in DSOL

[Bennie T. <B.J...@st...>]

Bastiaan,

In the constructor of your application, you can define some properties for
the animation window. So, for your example:

public class Application extends DSOLApplication
{
    public Application()
    {
        super();
	  //second parameter: Xmin, Ymin, X range, Y range

this.properties.put("dsol-gui.animation.panel.extent","10000;30000;10000;100
00");
        this.properties.put("dsol-gui.animation.panel.size","1020;680");
    }
}

There seems to be some sort of constraint on the values you can use for the
extent of the animation window; similar to the aspect ratio of a picture. So
while it displays correctly if the X range is the same as the Y range (as
above), it automatically adjusts the Y min if you have X range and Y range
values as in your example (10.000;20.000).

Regards,
Bennie

Dear DSOL developers and users,

I have some problems with understanding the working of the animation
panel. I want to set the dimension size of the AnimationFrame (so not
the default setting of 600 by 600). Next to that I want to able to set
the worldcoordinates visible in the frame. (for example xmin: 10.000,
xmax: 20.000, ymin 30.000, ymax 50.000).  How does these things work?

Then I have some problems with reaction of the grid on my renderable
objects, using for example

      >>public void paint(Graphics2D g, ImageObserver arg1) throws
RemoteException{

     >>   g.setFont(new Font("Arial Narrow", Font.BOLD, 320));
     >>   g.translate(1.0,1.0);
     }

also the grid numbers of the animation panel turns bold.
and also translate methods in a Renderable2D translates the complete
gridstructure in the same way.

Besides this,  I have another question: Is it possible to have another
animation panel with a different map/ renderables and a different scale
in the same model?

Kind Regards

[Dsol-java] example of a Mapfile.xml for GIS purposes in DSOL

[Bastiaan v. de R. <in...@ra...>]

Hello all,

I'm trying to insert my map (multiple layered CAD drawing) for 
animationpurposes (2d) in my model using the GISRenderable class. I know 
already that I have to convert the layers of my CAD drawing to 
shapefiles and then to make a mapfile. I have several shapefiles (.shp) 
and have the xsd schema( 
http://cvs.sourceforge.net/viewcvs.py/gisbeans/gisbeans/src/conf/mapfile.xsd?r1=1.1)  
of the mapfile, but it would help to have a example of a working mapfile 
(like there is an example of the experiment.xml file in the DSOL tutorial).
Does anyone has an example of a simple Mapfile (.xml) which can be given 
as an argument  to the GISRenderable class? Or does anyone know a 
project which uses the GISRenderable class which I could check out?

I hope someone can help me

Kind regards

RE: [Dsol-java] suspending a Process

[Peter H.M. J. <p.h...@tb...>]

Dear Fred,

 

You are not misunderstanding the concept. To see where stuff goes wrong, I
have two questions for you:

 

a)       are you using the development code from DSOL's CVS or are you using
the stable sourceforge version?

b)       Could you send me your Process code? I can have a look at it.

 

Kind regards,

 

Peter Jacobs

Subject: [Dsol-java] suspending a Process

 

I'm attempting to use a Process
(nl.tudelft.simulation.formalisms.process.Process). I see that the Process
code (Process.process()) begins to run in the Interpreter when
Process.resume() is called  the first time. I believe that the
Process.process() method eventually calls Process.suspend(), and that this
should cause the Interpreter to set aside the Process's stack and return
from the call to resume() in its original caller. However, this doesn't seem
to be working. Instead, theInterpreter throws SimRuntimeException. Am I
misunderstanding something?

[Dsol-java] Eclipse' suggestion of method arguments

[Bennie T. <B.J...@st...>]

Hi,

I got a question regarding the autocomplete function of Eclipse. I notice
that sometimes Eclipse's suggestions, when I pres ctrl+space, for the
arguments of a method only has the classes and not the argument names (as
assign during the method declaration).

For example, when I type this.simulator.scheduleEvent() and press
ctrl+space, Eclipse gives the following as suggestion: double arg0, Object
arg1, Object arg2, String arg3, Object[] arg4. But then I don't know what
each argument represents. In the java documentation, these arguments have
names and I would thus like Eclipse to rather suggest (as it does
sometimes): double relativeDelay, Object source, Object target, String
method, Object[] args.

Does anyone know how I can set Eclipse to always display complete
suggestions?

Thanks,
Bennie

[Dsol-java] value assignment--> just a very small question, but I just don't know the answer at the moment....

[Bram W. <Br...@We...>]

Dear group,

 

If I put this line in my code:

 

this.lastEntranceTime = this.simulator.getSimulatorTime();

 

I assign the left value to the right value, so they stay the same. I don't
want that.

How can I ensure that when I 'run' this line my lastEntranceTime will get
the simulator time, but remains constant afterwards?

 

Thanks,

RE: [Dsol-java] Measuring the transit time

[Dirk S. <di...@tb...>]

Joep,

I think you're asking two different questions:
Q) Where can I find the DSOL source code?
A) You can check it out from the sourceforge CVS; see DSOL project and
http://sourceforge.net/cvs/?group_id=77699

Q) How do I measure a transit time?
A) See our model; comparison 2. We measure the transit-time of containers in
our system. (we call it throughput time). Have a look at the code at the
bottem of ModelC2.java and our StatisticsListener.java.

Success,

Dirk

[Dsol-java] Still question

[Fu C. <col...@ho...>]

Hi everyone
I still got the problem in my model. The dsol Logger shows that 
nullPointerException in the line 144 of my Factory class. Here are the code 
of line 144:

this.inventory[(int)productType.draw()]=this.inventory[(int) 
productType.draw()]+1;

But Acually I already initialize inventory array and productType in the 
constructor of Factory class. I guess the problem might be productType cuz 
I use "switch"-"case" to initialize the productType. Following are the 
codes
switch(factoryNumber)
		{
			case 1:
				this.productType=new DistDiscreteUniform(stream,0,5);
				break;
			case 2:
				this.productType=new DistDiscreteUniform(stream,6,11);
				break;
			case 3:
				this.productType=new DistDiscreteUniform(stream,3,8);
				break;
			case 4:
				this.productType=new DistDiscreteUniform(stream,1,8);
				break;
			
			default:
		}
Can any one help me? My model is comparison 14 on CVS. Loek, last time your 
suggestion is correct.Thanks.
