Multi-block geometry from blender

Blender seems to be a good tool for creating geometry for CFD before meshing.
Is it possible with Blender to create a geometry that consists of two blocks which share a common face? Either by splitting a volume or by extruding a face of a volume or by glueing two volumes together. I hope this post is adequately placed in this forum. CFD people probably best understand why I would want such a geometry. Thanks for your hints. |

Hi,
yes, this should be very easy. We use this approach to define geometries with multiple volumes (e.g. conjugate heat transfer) which are then meshed with enGrid. To create such a geometry in Blender is straightforward and I am sure there is more than one viable method. If you know (learn) your way around Blender then it should be clear what needs to be done. A different question is how you can use the geometry for meshing. Cheers, Oliver |

Hello Oliver,
Thanks for your answer. I am used to more CFD-oriented CAD preprocessors like Gambit or ICEM where it is very simple to just split a block, insert vertices, faces etc.. It will take me some time to figure out how to do it in blender. I appreciate that it is not strictly necessary to have a real multi-block domain since with OpenFOAM one can stitch together sub-meshes. I do, however, like the idea of having a "nice" mesh at internal faces. -Sebastian |
