[petsc-users] Two DMDAs for conjugate heat transfer

[Xiao, Jianjun (IKET)]

Dear developers,

I am writing a CFD code to simulate the conjugate heat transfer. I would like to use two DMDAs: one is for the fluid cells, and the other one is for the solid cells.

Here are the questions:

1.  Is it possible to have two different DMDAs for such a purpose? How the data in these two DMDAs communicate with each other? Are there any similar examples?

2.  How to deal with the load balancing if DMDA is used? Or it is simply impossible?

Thank you.

Best regards
JJ
