[Libmesh-users] reading DG0 solution from a text file

[Ata o. M. <a.m...@gm...>]

Hi,

I'm trying to set the solution of a DG0 variable in an ExplicitSystem
(which I use for material properties) from a text (or CSV or really
anything else I can generate in Python) file. I saw that Moose has
something similar in ElementIDInterface
<https://mooseframework.inl.gov/source/interfaces/ElementIDInterface.html>.

 I'm not using distributed mesh for now, so each processor should have the
whole mesh, which I read from an exodusII file. Is there a way to access
element numbers in the exodus file (elem_num_map) given the element
pointer? Would you happen to have any better suggestions?

Thank you,
Ata
