Thank you very much for this preprint, Lawrence. I have also planned to use the pressure mass matrix for the A11 block. Unfortunately, at this time, I have no time for implementing things. What I would like to do is to get the best out of the built-in methods of fieldsplit/PETSc. Any hint is

Dear Petsc-gurus, I am solving Biot's poroelasticity problem : [image: Images intégrées 1] I am using a mixed P2-P1 finite element discretization. I am using the fieldsplit framework to solve the linear systems. Here are the options I am using : -pc_type fieldsplit -pc_field_split_type schur

Hi I want to install SLEPc but the configure command gives me the above error message: "Cannot mix release and development versions of SLEPc and PETSc”. What I understand from lecture of config/configure.py file in slepc the key is to compare “RELEASE” paramaters. In my petsc and slepc
