ANSA (Automatic Net-generation for Structural Analysis) is the leader in rapid, automatic surface & volume mesh generation and FEA preprocessing. Owing to its advanced features and innovative functionality it has become a standard in many industry sectors worldwide. ANSA offers unique functionality for efficient FE-model generation, leading to significant time reduction in Finite Element modeling and processing.
Geometric Associativity
One of the key aspects of ANSA is that the CAD (geometry data) and mesh are associated. This means that changes performed on the CAD will be reflected on the mesh, and vice versa. Unlike most other pre processors, in ANSA, mesh refinement is not just splitting elements, but a true refinement of the finite representation. Loads, boundary conditions, and connections (welds, etc) can be applied directly to CAD
Mesh Reconstruction
Optimize and reconstruct shell mesh:
Improve the quality of shell mesh (mesh on geometry)
Improve the quality of shell mesh (mesh on mesh)
Reconstruct mesh to coarsen. Also available in session file for batch process
Reconstruct mesh to smoothen mesh transitions
Remove triangles automatically from internal/external perimeters and spots
Achieve better directional mesh alignment
Automatic Connections Modeling & Assembly
Automatic weld spot recognition via CAD-data files
Connection file import
Automatic connection definition and application of alternative connection representation
Semi-automatic seem-welding
Mesh dependent and independent connection types
