Scan-and-Solve for Rhino

Simulate Early, Simulate Often... In Rhino

Compare with FEA

Mesh-based FEA

Scan&Solve™

Geometry approximated by the mesh of finite elements Native geometry is used
Pre-processing: heuristic simplification and meshing Pre-processing: none
Meshing must resolve all geometric errors and tolerances Geometric errors are irrelevant so long as points can be classified and distances to the boundary can be computed
Mesh size is determined by the smallest feature size Mesh size is determined by the desired resolution of the analysis model (uniform grid)
Small features must be removed Small features are preserved and handled automatically (resolved or ignored, depending on resolution)
Boundary conditions: enforced at the nodes only Boundary conditions: enforced on all points of the boundary
Derivatives: pre-computed Derivatives: pre-computed and run-time
Integration: Gauss points of finite elements Integration: Gauss points determined at run-time
Basis functions: local support Basis functions: local support
Sparse linear system Sparse linear system
Geometric accuracy control: fixed and limited by the mesh Geometric accuracy control: determined by accuracy of geometric computations (point test, distance); adaptive
Analysis accuracy control: h-, p-, and k-refinement Analysis accuracy control: h-, p-, and k-refinement
