Specific preprocessing programs are used to define the geometry and mesh of a problem. By using these programs, you can define varied and complex 2D and 3D geometries, as shown in Figures 1 to 5.
Because ATILA's geometric preprocessors are parametrized, you can use parameters to define geometrical entities. Consequently, you can modify all or part of the geometry just by changing a parameter's value, without having to reenter the entire geometry.
ATILA's automatic and assisted mesh generators help you create meshes that are well-adapted to your analysis.
