WebJul 7, 2024 · I tried the Built In engine + surface filling but I was not getting the surface I want. 2. I need to create a manual boundary layer from the surface so I would need to have transfinite recombined. 3.

WebDec 7, 2024 · I think the middle ground between a transfinite structured grid and a completely unstructured one would be one made of 8-node hexs. If your 3D case can be built from an extruded 2D case, you could try setting Mesh.Algorithm=8 to get right triangles (rather than equilaterals) and then use the Recombine Surface option to turn them into …
Webtransfinite algorithm to distribute the nodes following a geometric progression (Progression 2 meaning for example that each line element in the series will be twice as long as the preceding one). The optional argument `Using Bump expression' instructs the transfinite algorithm to distribute the nodes with a refinement at both ends of the line.
