[Simnibs-discuss] issues with installation (petsc_solver) and also meshfix-charm error

[Micki Gaby Pell]

Hi.
Two questions please.

1) I am having problems installing simnibs-4.0 on a PC. Installation fails
with the following error:
ImportError DLL load failed while importing petsc_solver. The specified
procedure could not be found.

2) When running charm on a PC with simnibs-4.0 successfully installed, the
process is failing towards the end with the following error related to
meshfix:

Any suggestions what might be causing these two problems?

Thanks
