If it takes 20 hours and it's not finished yet this is not something you will be able to solve with more RAM. I did some tests on simple files and there is no multi-core meshing phase in it. I would say use different software for now capable of providing tools for efficient mesh operations. Use FreeCAD for more simple objects where solids are made and manipulated in more reasonable amount of time. Or maybe there is faster software available you could use for one of the phases and do the rest in FreeCAD. Or to reduce the complexity of imported mesh...hemocyanin wrote:I guess I'll be buying more memory so none of the cores get starved and start hitting swap.
Doing one operation for 20 hours sounds a bit unreasonable to me if you would like to do operations like that on regular basis.
