v1.04.119 PETSC04 - Validating the FIELDSPLIT preconditioner from PETSc

Summary:

This test case makes it possible to validate the operation of the preconditioner FIELDSPLIT of the solver PETSC. This is a very general framework for dynamically defining block preconditioners. We refer to the

documentation for using the SOLVEUR keyword, [U4.50.01].

The test includes 4 models, making it possible to verify the correct functioning of the solver:

• petsc04a, Stokes problem sequentially

• petsc04b, Stokes problem in parallel

• petsc04c, problem THM sequentially

• petsc04d, problem THM sequentially

• petsc04b, Stokes problem in hpc

• petsc04d, problem THM in hpc
