I'm trying to get a 3D mesh working of an aerofoil. Gmsh, CfdOF, AirPlaneDesign.
Code: Select all
OS: Ubuntu 22.04.1 LTS (ubuntu:GNOME/ubuntu)
Word size of FreeCAD: 64-bit
Version: 0.20.1.29410 (Git) AppImage
Build type: Release
Branch: (HEAD detached at 0.20.1)
Hash: f5d13554ecc7a456fb6e970568ae5c74ba727563
Python 3.10.5, Qt 5.15.4, Coin 4.0.0, Vtk 9.1.0, OCC 7.6.2
Locale: English/United Kingdom (en_GB)
Installed mods:
* Plot 2022.4.17
* AirPlaneDesign 0.4.0
* CurvedShapes 1.0.4
* CfdOF 1.18.0
My (failing) procedure:
1) Using AirPlaneDesign create a NACA aerofoil extruded to 3D.
1a) Checked that it is a "Solid". Geomtery check gives 0 failures or issues.
2) Create a cube surrounding the aerofoil.
3) Cut the aerofoil into the 3D cube. The cut is the surrounding cube that I want to mesh. The aerofoil is a surface, its internal space wont be meshed.
4) Use gmsh to mesh the Cut (the cube with the aerofoil cut out.
5) Open the resulting mesh in Paraview.
At this point Paraview shows that the internal cut of the aerofoil is not an aerofoil but a cube or bounding box of the aerofoil's shape.
So My mesh is the cube with an inner bounding box cut out.
Any help or pointers to get the aerofoil meshed properly for CfdOf ?
