You error message says, that it cannot open a file during the simulation (also it doesn't mention, which file cannot be opened, which is not very user-friendly praxis of coding ;-)) and opens some potential for code improvement). Maybe you did some file system operations while the simulation was running, altering some file pathes?

This is FORTE package of Ansys. This is a blackbox software, where user does not have any control on software codes.

So, it is very difficult to identify where the problem is. Lalmi Djemoui Thomas Frank
