ngsolve with Conda cannot find mumps

I’ve been using ngsolve by installing with Conda. However, it can’t seem to find mumps. I installed mumps via Conda, but ngsolve still can’t find it. Is this normal?

the ngsolve conda installer is without mpi. I guess you want to use mumps for mpi parallel solve? Then you need to compile ngsolve manually right now.


I can get by without it for now. I was mainly asking as a replacement for Pardiso, because I was getting some weird errors (mentioned in another post).


You can use umfpack (included in most installers, needs sparsesuite dependency) or if you have a spd matrix the included sparsecholesky.

For some reason there is no conda installer for umfpack for windows. It’s not a big deal.
