First of all thanks for the attention yugi.
I tried your command but it did't work, but I think I founded the issue (maybe)
Typing python3 didn't work for me (I think because I already use python 3 as py).
So I typed in the shortcut renamed Telemacv8p1r1:
1) py C:\opentelemac-mascaret\v8p1r1\scripts\python3\compile_telemac.py
but it came up with the error1 (attached figure)
2) So I typed
2.1)cd C:\opentelemac-mascaret\v8p1r1\scripts\python3
2.2) py compile_telemac.py
But again it came up again with an error (error2, attached figure)
In the last line of the error2 you can see that it's saying that the file ''systel_v8p1'' could not be found (my mistake, cause I both change the directory and also had renamed the file in ''systel_v8p1r1''
)
3) So I
3.1)rechanged the directory (cd C:\opentelemac-mascaret\v8p1r1)
3.2)renamed the systel file in ''systel_v8p1''
4) and run the command
py C:\opentelemac-mascaret\v8p1r1\scripts\python3\compile_telemac.py
And......it finally works!!
P.S. for launching the simulation I just have to type:
py C:\opentelemac-mascaret\v8p1r1\scripts\python3\telemac2d.py
and the the name of the file .cas
P.S. 2
Just for be clear in the various folder or path there is v8p1r1 just because I renamed the folder with that name (instead v8p1)
Sorry for the long reply but that is just for help any other who may have my kind of problem.
Thanks again yugi,
Andrea
