Neper conjunction with comsol

[MII1187]

Hi，
I want to import the polycrystalline model generated by the neper software into the comsol for simulation, is there any way to achieve it?
Thank you

Not with Neper itself.

Hi !
I encountered the same problem as you, did you solve it?

[MII1187]

Yes. Convert tess files to stl files. But this method only works for 3D models.
neper -T -n 10 -id 1 -domain "cube(1000,100,100)" -format stl

Thank you very much for your reply, it has helped me a lot

hello, I generated a tess named n100-id1.stl by using your command 'neper -T -n 10 -id 1 -domain "cube(1000,100,100)" -format stl' , but the stl file can't be open by rhino or other available apps

I‘m sorry that I don't konw why it didn't work，when I use -format stl, the tess would be output as a .stl file which can load in COMSOL, maybe you can try other simple commands or check the neper installation, this is my personal small suggestion, hope it helps you.

thank you! I luckily resolved this issue yesterday by correcting the head and the end of the ASC II file
