How to generate a TPMS Structure in formats other than STL with not many faces suitable for ANSYS

      I needed your idea about an issue that I have faced lately. When I generate a PMS lattice in MATLAB, I can export the geometry only as an STL file which can be used both for 3D printing and simulation. But the problem is that the STL files generally have many faces (Minimum 20,000 faces for one coarse usable cell in my case). And it makes the ANSYS very slow cause dealing with many faces takes a lot of RAM for each step of the simulation including generating a mesh and generally all calculations. I tried merging the faces in ANSYS but my laptop (with 32 GB RAM) hung so I had to cancel it. The PMS lattices are made of implicit functions (For example: f(x,y,z)=c or -c

      If you have STL, you can use reverse engineering tools in SpaceClaim to create geometry.
