[petsc-users] [petsc4py] DMPlex and DT class

[Valerio Barnabei]

Thank you Matt,
I've read some of your works and  I'm interested in your approach. I would
like to keep in touch with you, both to consider the option to make python
interfaces for DT class, and to have a deeper understanding of Sieve.

Best regards,
Valerio Francesco Barnabei

Hi Valerio,

There are no Python interfaces for DT because it is all experimental code.
We have not yet agreed that this is
the correct way to do things, so its all my own C experimentation. I could
help you understand it to make Python
interfaces if you wanted to.

  Thanks,

    Matt

experiments lead.
