Geometry

Simcenter STAR-CCM+ imports geometries from, and integrates within, leading CAD and PLM systems. Simcenter STAR-CCM+ also offers a built-in capability for modifying and creating CAD geometries directly.

Geometry Import
Simcenter STAR-CCM+ reads geometric data as follows:
  • Native formats: CATIA V4 and V51, Siemens NX1, SolidWorks1, Autodesk Inventor1, PTC Creo1, Rhino 3D1, and Solid Edge1
  • Neutral formats: IGES, STEP, Parasolid, IDF, and JTOpen1
  • Triangulated formats: STL, CATIA graphics .cgr1, pro-STAR .dbs/.inp, Nastran and Patran shells .nas & .pat, Medina .bif1, FELISA .fro, VDA-FS1
  • PLM formats: 3DXML1, PLMXML
  • Automatic error check and healing
CAD Clients
CAD Clients are available as Simcenter STAR-CCM+ add-ons embedded within leading CAD systems. CAD Clients provide bi-directional and associative geometry data transfer. The supported CAD systems are: CATIA V5, Siemens NX, PTC Creo, and Autodesk Inventor.
Geometry Modification and Creation
3D-CAD is a parametric feature-based modeler that is built upon the Parasolid kernel. 3D-CAD works on both Linux and Windows, and is fully integrated within the client-server architecture of Simcenter STAR-CCM+. The extensive suite of CAD functions include:
  • All relevant operations for creating parametric feature-based solid and sheet bodies
    • Sketching, extrusions, revolving, lofting, sweeping, and imprinting
  • Body operations: patterning, transforming, Boolean actions, and imprinting
  • Multi-surface freeform surface modeling: U-V mesh deformation with edge constraints
  • Import and edit 2D and 3D curves
  • Defeaturing and sewing tools for imported geometries
  • Automatic blade slicing tool for rotating machine geometries (using blade faces or blade sketches)
  • Automatic removal of small bodies or surfaces irrelevant to simulation
  • Flow domain extraction
  • Colors assigned in the CAD packages are imported by default. You can assign or edit colors within 3D-CAD modeler
  • Interactive Sections and Exploded Views for examining the inside of a complicated body or viewing how assembly bodies interact with one another.
  • CAD repair features for geometry simplification
  • Measuring tool
  • Metadata support
