Hi Ana,
If you enter graphical output step in your cas file the simulation while running stores the results file in a temporary directory within the run directory. As you are using parallel processing it will create sub domain results file for each processor which you can open in BK as a slf formatted file and view all of the output result files. There is probably a python script program available in the telemac system to load all of these sub-domain result files and compile as one. The files have a name T2DRES00006-0000, T2DRES00006-0001 etc. This will alow you to view the simulation rather than waiting for the run to finish.
I am not sure about a fortran option
regards
