[petsc-users] possible to save direct solver factorization for later use

[Randall Mackie]

Is it possible to save a direct solver factorization (like Mumps) for use in later parts of a code?

In general, I’m thinking of a scenario like this:

mat A - do lots of solves using Mumps

mat B - do lots of solves using Mumps


	do other stuff

mat A - do lots of solves using Mumps

mat B - do lots of solves using Mumps


If possible, I’d rather only do the numerical factorizations once, and then reuse as required.


Do KSPView and KSPLoad to/from binary files save this information?


Thanks, Randy
