Meshing complex geometry using SOLIDWORKS and STAR-CCM+

Build the CAD model in Solidworks.

1, In excel, transform airfoil data into mm, and add z coordinate;

2, In Solidworks, insert->curve->curve through XYZ points;

3, Open a sketch, convert entities (convert the curves into sketch lines);

4, Close the trailing edge;

5, Features, extrude the airfoil to a wing

6, Open a sketch on the top plane, plot the region to be cut;

7, Extrude the region to be cut (!!!!!!DO NOT MERGE RESULT)

8, insert->Features->Combine subtract the tip region

9, insert->Feature->move/copy rotate the AoA

10, Do a similar thing for the computational domain (!!!DO NOT MERGE when extruding)

11, Save as a step file

Meshing in STAR-CCM+

1, Open star-ccm+

2, import surface mesh

3, Geometry->Parts->Combine2->Surfaces->Face  split by patch

4, Geometry->Parts->Combine2 (right click) Assign region to parts

5, Geometry->Operations->Automatic mesh, Combine2, select surface Remesher, Tetrahedral Mesher, Prism Layer Mesher, set default controls; enable curvature derivation distance, minimum surface side

6, Custom Controls-> surface control, Do surface mesh control

8, Export mesh, select regions only, (!!!DO NOT select boundaries)

7, Geometry Parts->New shape parts->Cylindric, this part can be used for volumetric mesh control; some settings may be overwritten; for prism click only generate standard prism; Prism layer can only be one layer, use split in Nekmesh if multilayers are needed.

The resulting mesh is
