open TELEMAC-MASCARET The mathematically superior suite of solvers

Hi ...someone!

I'm trying to install the last telemac version following this video (with some adaptations) :

However, it didn’t work for me. But I think I'm close to the solution!

I tried to install the version v8p3r1. It goes well until compiling. Then it requires newer version of scypy, numpy and matplotlib. I installed them using "pip3 install --user XXX" and it worked. I recompiled and it worked but when I tried to run the Malpasset example it gave me this:

raise TelemacException('Could not find {}'.format(cfg_file))

I tried then to use one of the systel file as "systel.cfg" (systel.edf.cfg seemed to work best) but I get the following error:

I checked that "geo_malpasset-large.slf" does exist and it does.

Do you have any idea?
Thank you very much for your answer.

Best regards

Thanks to M. Maskell, my problem is solved !

Hi Pierre-Adil,

I don't have this problem as I am still running the scripts using Python27. However, I got the same error using Python3. It seems to be a relative path problem. As you are running the code from "C:\opentelemac-mascaret\v8p0r0\scripts\python3" it is looking for the geometry file in that folder. You can try 3 things (Note that I have only tried the first option which worked for me).

Open the file "C:\opentelemac-mascaret\v8p0r0\scripts\python3\telemac2d.py" and add the following two lines to the top of the file:
import sys
sys.path.append( sys.path.append( "C:/opentelemac-mascaret/v8p3r1/scripts/python3/" )

Do this in a Python editor like idle or just use notepad.

Then run the code from the example folder itself but you will have to give a full path to the script so:

python C:/opentelemac-mascaret/v8p3r1/scripts/python3/telemac2d.py t2d_malpasset-fine.cas

Edit the .cas file and give full absolute paths to the input files.
Open the file "C:/opentelemac-mascaret/v8p3r1/scripts/python3/telemac_cas.py and comment out the lines 177 to 180.
# if not path.exists(val):
# raise Exception(\
# "In {} missing file for {}:\n {}"\
# .format(self.file_name, key, val))
These should be considered temporary fixes to hopefully get the model running. However, there should be a better solution for running the Python3 version. I am not familiar with this version but it seems others on the forums have had the same problems.

Let me know if it works.

Regards,
John
