Rhino and ansys fluent (CFD)

can I create a high-quality mesh within rhino or grasshopper or any add-on for grasshopper for the mesh generation and verification or do I have to use meshing software?

note: it’s an architectural project targeting indoor air quality simulation (airflow distribution, particle dispersion…etc). the geometry will be created using rhino + grasshopper

Hello - if a quad mesh is what is needed, you may be able to use QuadRemesh in V7 to get a good evenly distributed mesh where Rhino’s built in mesher may give you too much variety. In Rhino’s settings, you can control things like aspect ratio and maximum edge length (in the detailed controls) but joined or trimmed faces will always include triangles at least at the edges.
