3d mesh problem using readmesh3/savemesh in Windows 10

[ydm (Daoming YU)]

Thank you for your reply.

I think I didn’t ask my question clearly. It’s not about which mesh file format can be imported into FF++. My problem is that readmesh3 and savemesh functions are not working in Windows 10 system.

I think other users had the same problem a few days ago:

Error of savemesh in 3D

Hello!everyone, I install windows version FreeFem 4.11 in win 10. But there is something wrong when I save 3D mesh. So I test the following simple code: load "msh3" load "medit" mesh3 Th3=cube(10,15,5); plot(Th3); medit("Th3",Th3); savemesh(Th3, "surf.mesh"); The program is terminated when it runs to savemesh, then I get a empty surf.mesh file with 0KB, I don’t know what the problem is？ Thank you in advance.

Problem reading/writing mesh file

I ran this code on my computer But when I open the saved grid file, it is blank. I don’t no why.
