Hi,
The error indicates the ifort.exe compiler is not in the environment path variable.
Have you installed ifort compiler on your system?
If yes then you will have to set the ifort compiler path in the path environment variable. Find the ifortvar.bat file in the intel compiler installation directory, which will give you and idea as how to set the compiler path and other settings.
To run the simulation (as indicated in the run error snapshot), the fortran file specified in the steering file has to be compiled and linked with telemac code, for which a fortran compiler is required (for example gfortran or intel fortran).
With Best Regards,
Gourish
