When carrying out calculations such as aerodynamic analysis, etc., the more meshes there are, the more time it takes to calculate and thus increasing the computation costs. By using HexCore, you can reduce the number of meshes. Use Tet Mesh or boundary layer mesh within the vicinity of the analysis target, and use hexahedral cells in the other areas.
1. Go to Mesh > HexCore
2. Select Keep Outer Domain
3. Select Grow Upto Boundaries and click Boundaries…
4. Select the boundaries of the outer frame, excluding the object to be analyzed, from the Outer Box Zones field (e.g. inlet, outlet, ground boundary, etc.).
Click Apply, then Close.
5. Select Delete Dead Zones from the Zones field in the HexCore panel
6. If Buffer Layers and Peel Layers are set to 2, good quality volume meshes can be generated
7. Decide the Max Cell Length, then click Create If you have already created a boundary layer mesh for the analysis target, create a domain from Mesh > Domains, before doing this work.
