I have made my file .cas in order to run the simulation. Initially telemac creates the directory in which copies the geometry, boundary condition, dictionary and steering file(T2DGEO,T2DCLI,T2DCAS,T2DDICO and out_telemac2d.exe)and everything is ok, but when it proceed it gives me the error:
"launch failed: CreateProcess(t2d_valcamonica.cas_2019-04-28-11h56min18s -n 1 C:\opentelemac-mascaret\v7p3\examples\telemac2d\valcamonica definitivo\t2d_valcamonica.cas_2019-04-28-11h56min18s\out_telemac2d.exe) on 'DESKTOP-PB3AKKB' failed, error 2 - Impossibile trovare il file specificato."
the problem i think is that can't localize the position of .cas file but i don't understand why, because previously has copied it in the temporary directory and, also comparing with other test case, the .cas file is saved in the same position inside the folder.
