Robot - Calculations: Frontal Method

This dialog presents individual phases of calculations:

Model reduction (renumbering of nodes and elements)
Definition of the stiffness matrix for individual structure elements
Matrix decomposition (frontal decomposition) K = L * U
Problem solving for successive load cases.

The frontal method solves the K * x = b linear equation system. The stiffness matrix K is decomposed (frontal decomposition) into the two matrices K = L * U (Gauss elimination procedure). This method is based on the element-by-element aggregation of the matrix , where Nele denotes the number of finite elements and K_e is the relevant element matrix.
