[petsc-users] Question about DMPlex for parallel computing

[Gong Yujie]

Hi,

I'm learning to use DMPlex to write a parallel program. I've tried to write a sequential code earlier successfully, but when to write a parallel code, there are many things different. There are some questions I'm curious about.


  1.  Are the functions as DMPlexCreateGmshFromFile() and other read from file functions reading in the mesh in parallel? Or just the root node read in the mesh?
  2.  Are there some examples available for distribute the mesh and create the correspondingly local to global node(or position) mapping ?

I'm grateful for your kindly help!

Best Regards,
Gong
