Multi-Domain Meshing With CF-MESH+

With the latest release 3.0, Creative Fields has released a new multi-domain meshing feature. The feature enables the generation of conformal interfaces between the multiple domains present in the geometry.

In addition, the method consistently handles baffles. It is available by switching on the meshing of multiple domains and baffles feature in the settings tree.

The feature enables the creation of both patches or face zones at a multi-material interface and you can choose the case that is best for your type of simulation. In general, baffles are best to be left as patches, and multi-material interfaces are often not needed, unless they are moving or rotating.

Consistent handling of internal interfaces can be used for generating anisotropic meshes where needed. For example, by defining the free surface as an internal interface it is possible to generate a fine high-quality boundary layer inside the mesh and greatly reduce the size of the mesh because it is not necessary to refine the mesh in all three spatial directions anymore. Another nice property is the alignment of the boundary layer with the geometry which also improves quality.

We have invested a lot of effort into making boundary layer meshing robust over internal interfaces, too. The layers check the topology of the interface and intersect wherever possible to generate the best possible layer topology and avoid collapsing layers in most situations.

Future plans

Of course, we continue working hard on providing our customers with the tools that increase their productivity and the quality of their work. Our future plans include:

  • Enable control of the number of layers generated at each side of an internal interface.
  • Blend topology at open-boundary edges of baffles.
  • Read curvature information from CAD data to improve automatic cell sizing based on curvature.
  • Improve the selection of the internal interface for the extremely complex case where the modification of the initial mesh is needed to generate the exact representation of the input geometry.

I hope that you have found this post useful and that it has made you curious to try out our latest CF-MESH+, designed to alleviate the pain of meshing. You can also subscribe to our newsletter to stay informed on our newest developments.
