[engrid-users] export becg scripts blender 2.63a/2.62

[Matteo M. <mer...@gm...>]

Hi to all!
i have a "little" problem trying to export a model from Blender.
I was following this tutorial
 http://engits.eu/wiki/index.php/Tutorials/Version1.2/Unstructured_Grids_for_OpenFOAM_With_Blender_and_enGrid
Of course i adapted the commands to Blender 2.62 (the default blender
version in ubuntu).
Then i installed in Blender the scripts 2.59 i found here
http://engrid.git.sourceforge.net/git/gitweb.cgi?p=engrid/engrid;a=commit;h=0ed74b30e075f7090769f48040abdadbdf39ad10
So importing the model in enGrid i received this error "smallest edge
length is 3.5".
Thinking it was a version problem i tried Blender 2.63a , installing
the 2.63a scripts, but the result is the same.
Could anyone help me?

Thank you

[engrid-users] Boundary layer in symmetry planes

[Mehmet A. Ak <akm...@gm...>]

Dear All,
I was trying Engrid for a while.
What I have noticed about the mesher which I believe is a big problem
, is the inability to mesh symmetry planes with elegant boundary layer
mesh. I have just noticed problem while I was trying to get a mesh for
flat plate case. The program generates a mesh but the mesh has some
distorted elements and I could not find a way to get a smooth boundary
layer mesh for this simple case. Let me briefly define the steps for
the mesh generation sequence. First I generated a rectangular prism
with Salome solid model program. Then I meshed the surfaces and save
the file in stl format. Then I opened the file in Engrid. The forward,
backward and upper surfaces were defined as inlet and outlet boundary
conditions and side surfaces were assigned as symmetry planes. Bottom
surface was defined as no slip wall. When I tried to make the boundary
layer mesh without erasing existing surface mesh the resulting
boundary layer mesh was generated with abnormal spikes.
Is there a remedy to cure this unlikely problem?
Sincerely Yours.

Mehmet

[engrid-users] enGrid 1.2.0

[Oliver G. <og...@en...>]

Dear mailing-list subscribers,

we have finalised the enGrid 1.2.0 release and the source code is now
available on our server:
http://files.engits.eu

Furthermore binary packages are available for openSUSE 11.0, 11.1,
and 11.2. These packages can be found in an openSUSE build service
repository:
http://download.opensuse.org/repositories/home:/ogloth

In the future we will publish regular bug-fixes for this release and are
planning to release 1.3 towards the end of 2010. The emphasis for 1.3
will be put on performance, robustness and documentation along with
small improvements that arise from daily support or engineering tasks.

Best regards,
Oliver Gloth

Re: [engrid-users] Fwd: Compling engrid from git

[Mike T. <mta...@en...>]

I don't know what the problem is yet, but if you want to accelerate the
compilation process, you can use "make -j2" since you have a dual-core
processor (-j4 for quad-cores).

What version of g++ do you use? Could you post the output of "g++ -v"?

Re: [engrid-users] Fwd: Compling engrid from git

[Emanuele T. <nuo...@gm...>]

I try to comment this line on guimainwindow.cpp

  freopen (qPrintable(m_LogFileName), "w", stdout);

Warning disappeared but cc1plus process still 99% cpu usage and it seems
blocked

Re: [engrid-users] Fwd: Compling engrid from git

[Emanuele T. <nuo...@gm...>]

I fetch git sources in this way

*git clone git://78.140.120.226/git/engrid.git
cd engrid
git checkout -b release origin/release*

Then i compiled netgen with build-nglib.sh script. After that qmake and make
on src directory

Re: [engrid-users] Fwd: Compling engrid from git

[Mike T. <mta...@en...>]

I just tested it here on a similar machine and it took about 5 minutes.
Our nightly build tests (which include git clone and 4 build tests
(debug+release with or without CGNS)) take about 26 minutes.

I also checked the warning messages we currently have in the master
branch and there don't seem to be any about freopen (altough this could
depend on the compiler version).

Which branch did you use?

Perhaps i have to wait c++. How much time does engrid (only engrid not
dependencies) compilation take? I'm on a 1800Mhz Intel Dual Core

Re: [engrid-users] Compling engrid from git

[Mike T. <mta...@en...>]

Those are only warning messages. They shouldn't prevent compilation.
Did you get any error messages?

While the QT packages from the repositories might work, I'm not sure
about the VTK packages.
We currently use VTK v5.4.2.

Have you tried our installation script, which is available here?:
http://engits.com/phpBB3/viewtopic.php?f=2&t=62
(If you've made a git checkout, you should actually already have it in
"engrid/src/scripts")

[engrid-users] a bug?

[Tomislav M. <tom...@gm...>]

Hello,

I have been using engrid to generate prismatic boundary layer on a 2D
tet meshes created in Salome-MECA using Netgen algorithm, and I get this
error in the middle of the boundary layer generation:

This seems to be a bug in enGrid


file: seedsimpleprismaticlayer.cpp
 line:140

What is the source of this error?

Thanks in advance,

best regards,

Tomislav Maric

[engrid-users] installation problem

[Tomislav M. <tom...@gm...>]

Hello everyone,

I'm running 32bit Ubuntu 8.10 and I have tried to install the engrid
binaries:

sudo ./setup

The installation was quick and without an error, but starting
start_engrid caused this error:

tomislav@icarus:enGrid_linux32bit_1.0$ start_engrid
/opt/enGrid/engrid: relocation error: /opt/enGrid/libc.so.6: symbol
_dl_out_of_memory, version GLIBC_PRIVATE not defined in file
ld-linux.so.2 with link time reference

Can someone please help me with this error?

Also, I'm thinking about compiling engrid but I have VTK installed under
ParaView and no env. variables similar to VTKLIBDIR and VTKINCDIR
already set in my shell (bash). Actually, ParaView is installed as a
ThirdParty software for OpenFOAM, so if anyone has some experience with
this, I would really appreciate some help.

Best regards,

Tomislav

[engrid-users] forum account

[Oliver G. <og...@en...>]

Hello Osman,

There appears to have been a misconfiguration with the forum software: 
It used the local machine as email server which might caused some 
spam-filters to block the activation email. We have changed this and now 
it should work properly (it did for a number of test-users we have 
created). Anyway, your account has been activated manually. If you have 
problems to login, please drop me a line.

Sorry for the inconvenience!

Regards,
Oliver

[engrid-users] new discussion board

[Oliver G. <og...@en...>]

Dear all,

As Mike already mentioned we do have a phpBB3 based discussion forum 
now. Unless somebody has strong objections, we would like to use this 
forum for discussions and help from now on. All existing posts to the 
mailing list have been transferred to the board "Mailing-list archive" 
inside the forum. New posts, however, should go to the "General 
Discussion" board. The mailing list will remain but in the future we 
would like to use it for announcements rather than discussions and 
support. If, for whatever reason, you have objections or problems using 
the forum, feel free to post your problem to the mailing list.

The new forum can be found from our website, or directly under 
http://engits.com/forum

Regards,
Oliver

Re: [engrid-users] throttle.geo request

[Oliver G. <og...@en...>]

Hello Mark,

Here are the *.geo file and the corresponding STEP geometry. Access to 
Sourceforge seems a bit flaky at times. We have moved to GIT for version 
control and the repository is now on our own server (here in the 
office). Mike is currently looking into setting up a PhpBB forum to 
(maybe) replace the mailing list. If your surface orientation is wrong 
you can reorient it; but I guess you tried that already. If the 
orientation is not consistent it means that your surface mesh is not 
water-tight. Again, we (mainly Mike) are currently working to have 
surface meshing integrated into enGrid with better control over the mesh 
density as well.

Best regards,
Oliver

Re: [engrid-users] About Engrid

[Mark S. <mar...@ft...>]

Hi Petri,

I had the same issue, but got it working on a relatively new 8.04
installation.  See the discussion archive from about a week ago:

https://sourceforge.net/mailarchive/forum.php?forum_name=engrid-users

I went through the steps suggested by Mike Taverne and got it running:
https://sourceforge.net/mailarchive/forum.php?forum_name=engrid-users&max_rows=100&style=nested&viewmonth=200903&viewday=3

I didn't specify a password; just pressed return.

An alternative approach (horrible, though it seems to me), is to install
WINE, and install the windows version.  It worked as a stop-gap, for me.

BR,


Mark.

1) Yes, there will be.
Actually, there already is and you can download it here:
http://engits.com/ogloth/engrid_1.0_i386.deb
It's just that I (or more precisely pbuilder) am not yet completely

2) I suppose you mean the netgen CVS.

It's "Dreieckerl":

But things have changed. netgen now uses svn and engrid uses git:

Re: [engrid-users] Using enGrid on OpenSUSE 10.3 64bit

[Mike T. <mta...@en...>]

The GUI console output is read from /tmp/enGrid_output.txt
Check that you have permission to write to /tmp and that the file is
there when you start enGrid.

[engrid-users] Using enGrid on OpenSUSE 10.3 64bit

[S. S. <str...@ya...>]

Hi,

I also had problems compiling enGrid_1.0 using opensuse 10.3 on a 64bit 
workstation. Since I believe it might be due to the fact that the vtk-qt rpm  
seems to use Qt3 instead of Qt4, I downloaded the prebuild version 

http://engits.com/ogloth/enGrid_linux64bit_1.0.tar.gz

NOW it's running fine!! Thanks for the nice software.

HOWever, I've got one more secondary problem using enGrid, for which I haven't 
found a solution yet. The problem is a blank output window on the left hand 
side. When I compare to the tutorial of the enGrid manual, I should see some 
information there sooner or later. This is not the case. 

In short my question are: 

--Do I really need the output-window? If not, how can I get rid of it?
--I like information about what's going on. If the output-window can provide 
that, how can I activate the output?

Like I said, so far I'm not missing anything, but I'm curious and would be 
happy about any help or hints.

regards
Swen

Re: [engrid-users] Possible bug

[Mark S. <mar...@ft...>]

I answered my own question.  The mesh I created in Gmsh, is ordered
through the thickness.  The 2-D elements, then, are quads; I selected,
'Create Prismatic boundary layer', but there were no triangles available
for meshing.

So, I guess my next question is:  Are there plans for hexahedral
boundary layer generation?

Thanks again for the software!

BR,

Mark.

[engrid-users] Possible bug

[Mark S. <mar...@ft...>]

Hi everyone,

First, thanks for the great software!  I'm enjoying using it!

I created an unstructured 2-D mesh in Gmsh, extruded said mesh (ordered)
to form first order wedges, 1 element thick, defined Physical surfaces
and saved the mesh.

I imported the mesh into Engrid, reversed the surface orientation,
inspected which boundary codes were to be used for boundary layers,
and hit, 'Create prismatic boundary layer'.

Engrid returned:

Error:  There seems to be a bug in enGrid.

file:  createvolumemesh.cpp
line:84

The 'output' window in Engrid shows:

creating boundary layer mesh)

preparing prismatic layer

deleting tetrahedral cells

relaxing mesh size : 0% done

deleting tetrahedral cells

deleting Operation 0x9e1d68
 

I check the windows version (using wine), it generates the same error.

So, should i submit a bug report via the bugtracker available of
Sourceforge? (I'm new to this!)

Best regards,

Mark.
