[petsc-users] Element to local dof map using dmplex

[Morten Nobel-Jørgensen]

Dear Matt

Did you (or anyone else) find time to look at our issue?

We are really looking forward to your answer :)

Kind regards,
Morten

Dear PETSc developers / Matt

Thanks for your suggestions regarding our use of dmplex in a FEM context. However, Matt's advise on  using the PetscFE is not sufficient for our needs (our end goal is a topology optimization framework - not just FEM) and we must honestly admit that we do not see how we can use the MATIS and the MatSetValuesClosure or DMPlexMatSetClosure to solve our current issues as Stefano has suggested.

We have therefore created a more representative, yet heavily oversimplified, code example that demonstrates our problem. That is, the dof handling is only correct on a single process and goes wrong on np>1.

We hope very much that you can help us to overcome our problem.

Okay, I will look at it and try to rework it to fix your problem.

I am in London this week, so it might take me until next week.

  Thanks,

     Matt

Thank you for an excellent toolkit
Morten and Niels
