Meshes with many blocks and few cells

[LucasLangnaese]

Hello, thank you very much for this powerful tool! I use it for FSI simulations of blood vessels. I create conformal structure meshes for my given fluid meshes. I do this by extruding the interface mesh for the fluid to the outside. So I get meshes with a lot of blocks but a maximum of 1 - 3 cells per block. However, as the number of blocks increases, the computing effort required for “automatic block detection” increases significantly. Is there a way to use the tool more optimal for such a purpose? (many blocks; max 1 - 3 cells per block) Best regards Lucas

Hi,

yes, large number of blocks cause slowness. You can try if Numba works and helps with speed (see the docs).

Alternatively, if you're just trying to create boundary layers, try to use the Shell Extrusion method in the Unstructured Grids add-on. Please note the limitations mentioned in docs.

Here's an example of the Shell Extrusion method in the Unstructured Grids add-on

Thank you, the Shell Extrusion method in the Unstructured Grids add-on is exactly the right tool for my problem.
