Importing Geometry

One of the possible starting points for the meshing process is to import surface data.

Surface data exists in many different formats. To import geometry into Simcenter STAR-CCM+, this data must be translated into a format that Simcenter STAR-CCM+ understands using a CAD translator.

There are several different types of surface data that you can import into Simcenter STAR-CCM+:

• Surface meshes
• Neutral format data
• Native CAD data
• XML data

For each of the above file types, the option to import the data as regions or to import the data as parts is provided during the import process. Progress that is made during the translation/import process can be reviewed and the resulting imported surface can be checked for errors if necessary. If problems are found, they can generally be fixed using the surface repair tools.

If the surface data resulted in regions and boundaries being created then they can be scaled, rotated, translated, or reflected in order to position them properly relative to one another. Surface data that is imported as geometry parts can similarly be manipulated before being assigned to regions.

Additional region-based manipulations are possible in order to make them conform with the requirements for multi-region meshing.

Surface data can be imported to complement existing volume meshes so that only part of the simulation domain requires preparation for volume meshing.
