Ansys SpaceClaim vs Simul8

Ansys SpaceClaim is a Windows 3D modeling application for engineers who want direct modeling without learning a complex traditional CAD system. It can create, edit, repair, and simplify geometry, including CAD models prepared for simulation, and it supports assembly design, sheet-metal tools, and surface modeling. For reverse engineering, it can autosurface mesh data and convert STL geometry to CAD. Manufacturing workflows include model preparation, jig and fixture design, and sheet-metal design and unfolding. STL tools can repair faceted files and prepare models for 3D printing. SpaceClaim also provides bidirectional geometry linkage with Ansys Workbench. Import formats include .dsco, .sat, .sab, .asat, .asab, .pdf, .igs, .iges, .ipt, .iam, .msh, and .tgz; export includes .dwg, .dxf, .CATPart, .CATProduct, .cgns, .xls, .xlsx, .msh, and .tgf. It is paid, pricing is on request, and a 30-day Discovery trial includes SpaceClaim.
