The U-D-T-V 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 tetras are simpler than hexas contact michael.lautsch[at]lautsch-fe.com
