Hello @AnnaFless, I did not have so much luck with the .stp exporter in FreeCAD. I think from an engineering perspective, the free alternatives are not there yet. But again, I will also say I have not spent munch time on openSource CAD.
Snappy HexMesh is nice, I have not looked into it so much because ICEM makes things very easy. But the SimScale implementation is great for “magical-press-a-button” and a mesh appears. I need to see what Snappy’s limitations are before it requires user scripting like blockMesh. Also, in Hex Meshing, I would like to specify non-linear functions along a block path to concentrate nodes to the boundary to make the layers to resolve the boundary layer.
My intention behind this question is: is there an openSource meshing software that can handle something on the order of 75 million cells with a UI.
Also, on a side note, is it possible to compile custom made solvers on SimScale’s OpenFoam?
