MULTIGRID MARCHING TETRA ALGORITHM MULTIGRID method 1986 - 2025 U-D-T-V = unknown displacement/temperature/velocity A Finite Element solution is the projection of a U-D-T-V to a finite dimensional vector space. It is calculated from forces and boundary conditions using Galerkin methods. Projection means that there is no vector closer to the U-D-T-V. download    Introduction to theory and practice of FE download    How to obtain good results with bad elements download    Russian Mathematics HOME contact michael.lautsch[at]lautsch-fe.com
