[petsc-users] ksp solve error with nested matrix

Sat Feb 11 11:27:19 CST 2017

I am now getting this error, which is complaining for an operation for the shell matrix. I have only specified the following operation for the matrix: “MATOP_MULT”.

I am calling the solver with -pc_type fieldsplit.

What can I do to move forward with the solution? 

Thanks,
Manav
