Witryna22 sie 2011 · implicit solution method. • Since the explicit time step size depends on the length of the smallest element, one excessively small element will reduce the stable time step for the whole model. Mass-scaling can be applied to these small elements to increase their stable time step. The implicit method is not sensitive to such small … WitrynaPart 2 Finite Difference Method: Fundamental Techniques We discuss one-factor PDEs in detail and their approximation by finite difference schemes.

"WitrynaImplicit analysis requires a numerical solver to invert the stiffness matrix once or even several times over the course of a load/time step. This matrix inversion is an expensive operation, especially for large models. Explicit doesn't require this step. Explicit analysis handles nonlinearities with relative ease as compared to implicit analysis. " - Implicit finite element analysis
