Surface Projection in CFD-GEOM

The Project Surface tool of CFD-GEOM allows the projection of a single surface onto a collection of surfaces. The collection of surfaces may contain gaps and overlaps, and the resulting projected surface will then covers these imperfections.

Exporting STL Files From CFD-GEOM

A CFD simulation process starts from an accurate representation of the boundaries that usually originates directly from CAD systems. STL and IGES are two of the most common output formats used as a starting point for mesh generation. STL (StereoLithography) files represent 3D surface geometries using a triangular mesh allowing unambiguous transfer of files from one system to another.

Surface Trimming Utilities and Shortcuts in CFD-GEOM

CFD-GEOM provides several surface and trimming loop creation tools. Surface creation and trimming can be greatly simplified, depending upon what you want to do with the surfaces.  In most of the cases, surfaces are used to generate unstructured triangular and quad meshes on trimmed surfaces. 

Edge Linking in CFD-GEOM

In CFD modeling and analysis, there are times you would like to change the grid and re-run the case. These studies require coarsening and/or refining of the grid on the same model. In complicated 2D or 3D structured grid, changing the edge distribution on individual edges can be time consuming. Matching the same edge distribution on all edges in the group by changing the distribution on the edges one by one can become cumbersome. This work can be made very simple and quick by using the Edge Linking tool in CFD-GEOM.

One-click meshing with the CFD-GEOM Tet mesher

For unstructured geometries with more than one domain, you can individually mesh the surfaces and volume for each domain. But if you do not need fine mesh control, you can simply use the Tet Meshing tool to directly mesh all surfaces and domains at once.
