Hello all,
I want to reuse the factorization of a PETSC/MUMPS solve for different
right-hand side vectors. I found the following discussion:
https://groups.google.com/g/dealii/c/Sw0wHKEFuiA
and the issue: https://github.com/dealii/dealii/issues/2869
However, it's quite old. Is there a way to do it properly ? For example,
an option as keep the factorized matrices outside of the solve method ?
Thanks,
Best,
Yann
