Mat Foundation group
Used to create mat boundary, meshing and specify analysis and design parameters to analyze and design mat slab. Mat module uses finite element analysis technique for accurate results. The modeling of mat foundations is done through physical modeling.
Note: Rectangular Mat foundation jobs can also be created quickly using the Mat Foundation modeling wizard
.

Mesh Generation
As Mat foundation module is based on FEA analysis, program needs to generate plate elements. STAAD Foundation Advanced has automatic mesh generation tools and it can generate both quadrilateral and triangular mesh for any shape and size.
Mesh regions are used to create mat boundaries, holes, control regions etc.
