Dear @prj-, I have noticed that KSPSolveTranspose() does not work properly on a MatNest (using -ksp_type preonly -pc_type fieldsplit -pc_fieldsplit_type schur -pc_fieldsplit_schur_precondition self. I get the correct solution for KSPSolve(), but not for KSPSolveTranspose(). Is this a bug or expected behavior?
