Hi Barry and Matt,
Would you please give me some advice on the functions I need to use to
set different dof to the specified nodes. For now, I use
DMPlexCreateSection that dof is uniform throughout the domain. I am a
bit lost in choosing the right DMPlex functions, unfortunately.
Thanks and regards,
Danyang

Thanks, Barry. DMPlex also works for my code.

No, you would need to use the more flexible DMPlex

Dear PETSc Users,
Does DMDA support different number of degrees of freedom for
different node? For example I have a 2D subsurface flow problem with
the default dof = 1 throughout the domain. Now I want to add some
sparse fractures in the domain. For the nodes connected to the
sparse fractures, I want to set dof to 2. Is it possible to set dof
to 2 for those nodes only?
Thanks,
Danyang
