[snappyHexMesh] Creating stl file for snappyHexMesh from xyz coordinates

Vignesh2508 · April 19, 2017, 14:40

Hello Guys,

I have to generate a stl file for sHM. I have xyz coordinates for the model. Right now I wrote a code in gmsh to generate a geo file and then convert that into stl file. But that code generates a whole solid stl file. And that has a huge size which is unnecessary for me since it is only used for snapping the profile in sHM and I am going to use the stl file in sHM to do an external flow analysis. A simple thin sheet like extrusion will be enough for my simulation, which will also save a lot of file size. Is there a way to do that?

Thanks

Vicky

does the searchableBox work for your case?

edit: *not a stl, but you can define walls with 'user defined regions'

Hi Kal,

I know the feature that you mentioned. My geometry is complex therefore i need the stl file.

Anyway thanks

Vicky
