 Re: [Anuga-user] xMomentum and yMomentum in results From: stephen Roberts - 2009-09-27 23:00:48 ```Hi Peter, Actually the quantities xmomentum and ymomentum are "defined" as height times x velocity and height times y velocity. But as density of water is essentially taken as constant, there is a direct relationship with momentum, or at least momentum "density". To calculate the amount of momentum in a triangle you would need to multiple the area of triangle with height of water times density of water times velocity of water, i,e, our momentum quantities times area of triangle times density of water. At some time in the development of anuga we made the decision to call these quantities "momentum" as it seemed more in keeping with what the equation was trying to conserve.

 [Anuga-user] xMomentum and yMomentum in results From: Peter Wells - 2009-09-25 11:21:21 Attachments: Message as HTML ```Hello all, I'm trying to create plots of flow and speed from anuga SWW files and am having some confusion regarding the units of the xmomentum and ymomentum. The manual says that speed can be calculated using the following expression: quantityname = ’(xmomentum**2 + ymomentum**2)**0.5/(stage-elevation+1.e-30)’ #Speed If this is the case then speed = momentum / depth or ms-1 = kg.ms-1 / m which doesn't seem to make sense. The equation in the manual seems to suggest that the xmomentum and ymomentum variables output are in fact the flow per unit width in the x and y directions in which case this would make sense: m2s-1 / m = ms-1 Would it be possible for someone to clarify what SI units are used for the output vaiables xmomentum and ymomentum in the SWW file please? Kind regards, Pete ```

 [Anuga-user] How to load DEM data into ANUGA [SEC=UNCLASSIFIED] From: - 2009-09-16 02:33:35 ```Hi Listers, I have been talking to an ANUGA user off-list about certain problems the user is facing. Now that I have an answer I'm posting to the list to make the answer visible to the world! The user's question was "how do I load DEM data into ANUGA?". This is not too obvious, but after reading through the manual I have found example code in runcairns.py (pages 22,23 of the current manual): # convert a DEM file to a PTS file # note that the DEM filename is assumed to be project.demname+'.dem' # look in project.py for the value of project.demname dem2pts(project.demname, use_cache=True, verbose=True) # create the domain domain = create_domain_from_regions(...) # set up initial conditions domain.set_quantity('elevation', filename=project.demname + '.pts', ...) So the basic idea is to convert the DEM file to PTS data and then set the initial elevation from the PTS file, as shown. Ross ```

 Re: [Anuga-user] Anuga [SEC=UNCLASSIFIED] From: Glenda Besana-Ostman - 2009-09-15 02:55:04 Attachments: Message as HTML ```Thanks a lot! Yes, I would like to know how to run it and what kind of data and data format it needs. And what are the limitations and/or assumptions within the algorithm. Most of the simulation software I used runs on Linux while most of the students and public who needs and wants to learn it have Windows PC so I am really interested in using this. Thanks a lot for the manual and I'll email you about my progress. I hope you won't mind me asking more questions in the future. More power and kudos to all of you who developed and freely released this software!

 Re: [Anuga-user] questions about earthquake tsunami function [SEC=UNCLASSIFIED] From: Herve Damlamian - 2009-09-03 23:58:19 Attachments: Message as HTML ```Hi Fabrizio, Here are some tips that I hope will be useful to you: - "I have imported from anuga.shallow_water.tsunami_okada "earthquake_tsunami" and "Okada_func" for this problem, is it correct?" Yes, you don't need anything else. If you need an example to see how it works, you can look at the file test_tsunami_okada.py in ...anuga\shallow_water\ - "I don't understand if the variable z0 is necessary, or if are sufficient the x0,y0 and depth to fix the position of the fault" You need Zo since it defines the vertical origin of your model. Zo is usually equal to 0. Hope this help. Cheers Herve -----Original Message----- From: Jane.Sexton@... [mailto:Jane.Sexton@...] Sent: Thursday, 3 September 2009 21:02 To: herve@...
