Characteristics of modeling

3D Modeling_ THM

A thermo-hydro-mechanical problem is modelled. A preconditioner with 3 levels is defined that treats the components DX, DY, DZ in a grouped manner, the component PRE1et the component TEMP. Several levels of preconditioner are defined: an external preconditioner of the Gauss-Seidel type, an iterative GMRES method preconditioned by Jacobi for temperature, a Schur-type preconditioner based on an approximation of the Schur complement in pressure that is preconditioned by a Jacobi method and a multigrid method for movements.
