Collection of geometries 2D and 3D, mostly for Computational Fluid Dynamics.

In the document img.pdf, you can see some illustrations of geometries of this repository. We decided to represent all the geometries by a triangulation of the surface of the geometry.

Formats

• .hdf: This is the studies format of the CAO Software Shaper, from the Salome platform.
• .brep: This is a representation of a solid by its surfaces. This is at least readable by Gmsh and Salome.
• .step: This is at least readable by Gmsh and Salome.
• .geo: This is a CAO format. This format is readable by Gmsh.

I can assure you all the .geo files work well with the 4.9.5 version of GMSH. I can not guarantee the result with other versions.

WARNING: in some .geo files, you also can find informations linked to the mesh. I invite you to delete those sections if not needed.

Geometries 2D

C?_2D

These are elementary test geometries.

NACA_2D

Find more information on the NASA-NACA website. The geometry made here is the one with x between 0 and 1.

Geometries 3D

C?_3D

These are elementary test geometries. There are some lines about mesh at the bottom of the .geo files. You can easily remove these lines to get only the geometry.

• _Surface.geo: This is a geometry with a surface mesh, made with transfinite (ex: C6_3D_Surface.geo).
• _inSphere.geo: The volume is now the space between the geometry (the object) and a farfield sphere (ex: C6_3D_inSphere.geo).

Attention: C1_3D for exemple is not a 3D extension of C1_2D.
