v1.04.117 PETSC02 - Validating PETSc with the distribution of the assembled matrix

Summary:

This test case makes it possible to validate the operation of the solver PETSC with the distribution of the assembled matrix. It includes three models. Among them, three concern the elimination of boundary conditions (AFFE_CHAR_CINE) and validate the use of multi-grid preconditioners ML, BOOMER and GAMG. C modeling is also based on the dualization of boundary conditions (AFFE_CHAR_MECA) and is used to validate the LDLT_SP pre-conditioner. D modeling applies a Neumann loading (pressure).

Moreover, each model validates all the methods of distribution of elementary calculations (by groups of elements, by mesh).
