Output for visualization from python

joelbrown

Hi,

Is there a way that you know of to output the ISSM model data (md.*) in *.vtu format in Python? I don't have access to Matlab on the server that I am using and I would like to compare the results of assimilation runs for GrIS to other models that output results in *.vtu.

Thanks,

Joel

vtu is not supported, I have written a function to export the models in vtk format. I have duplicated the matlab (that I use) in a python function, you can test that and let me know if it works or if I have to do some modifications.

That sounds great Basile,

Where can I get that function? I will certainly test it for you.

Thanks.

Hi Joel

The function lives in the "m" part of src, following is the complete path on my build: trunk/src/m/contrib/paraview

I will not be arround for the next two weeks and the code is pretty buggy (Mainly syntax error) so I hope you can debug that by yourself.

Hi Basile,

I found the exportVTK script at $ISSM_DIR/trunk/src/m/contrib/defleurian/paraview/exportVTK.py, but it's giving me a syntax error (as you mentioned):

  File "/opt/issm/trunk/src/m/contrib/defleurian/paraview/exportVTK.py", line 6
    def exportVTK(filename, md, *args, enveloppe=False, **kwargs):
                                               ^
SyntaxError: invalid syntax

which can be fixed by putting *args behind enveloppe=False. I haven't had time to look through the rest of the script (it's very long!) but was wondering if a) you have an working version and can push it up to subversion, and b) if there is any way to contribute bugfixes back to ISSM. Just don't want to keep reinventing the wheel 😃
