[petsc-dev] Problem about DMPlexCreateExodusFromFile()

[Gong Yujie]

Hi,

I'm learning PETSc DMPlex module recently. A problem occurs to my PETSc when I'm using  DMPlexCreateExodusFromFile() to import a mesh file. I've tried to generate a mesh with Pointwise and ICEM, but both mesh files can't be input to PETSc. The Error code is :

[0]PETSC ERROR: --------------------- Error Message --------------------------------------------------------------

Looking forward to your reply!
