- Perform inspections of the structure: self-intersections and free boundaries are not allowed.
- Make a solid of the structure.
- Make the fluid domain based on points and create a box of it.
- Cut the domain with the structure.
...
- FMS file (best input for cfMesh) preparation
- Open Salome and load in the CAD model with the fluid domain. (docs/solarPanel.brep)

Table 1: Mesh quality and creation comparison CfMesh and SnappyHexMesh including boundary layer for 0[deg] rotated solar panel array.
Layers vs (no Layers) | CfMesh (OS) | SnappyHexMesh (example) |
No. layers requested [-] | 10 | 7 |
Expansion rate [-] | 1.3 | 1.3 |
CPU time [s] | 292 (110) | 6398 (3630) |
Grid cells [mil.] | 9.5 (5.5) | 12.3 (10.9) |
Hex [%] | 95.7 (94.8) | 96.7 (97.1) |
Max. aspect [-] | 162.4 (6.8) | 23.2 (5.8) |
Max. non-orthogonal [deg] | 79 (56) | 65 (58) |
Max. skewness [-] | 2.66 (1.78) | 20.5 (16.5) |
It has to be said that the CPU time increases a lot when increases either the expansion rate or the number of layers.
