Hi,

i would like to use NGSolve with Windows 10 and am trying to build it from sources (because i want to use MPI/PETSc).

Unfortunately cmake cant find the METIS-package (but is is installed).

Would you guys have an idea for solving this?

Thanks,
joey

Are you sure you want to use windows for this?

This comes on the petsc documentation if you search for installing on windows:

Installing PETSc On Microsoft Windows
Are You Sure?
Are you sure you want to use Microsoft Windows? We recommend using Linux if possible (and minimize troubleshooting Microsoft Windows related issues).

I had once a mpi - windows NGSolve installation running (without petsc), but it needed quite some adaptations and was quite some work… If you are sure you want to go through this I can search for my modifications… But I would recommend using linux.

Hi Christopher,
thanks for the advice!
I installed ngsolve now on the linux subsystem of windows (wsl version 2 with ubuntu 18.04) and this works :slight_smile:

best regards,
