Hi libmesh developers:
I use libmesh to code a biot problem, which is running well in sequential.
Now, I want to convert this code to parallel, I have the following
questions:
In my code, I use some std::vector values to store the derivatives on gauss
points inside every elements. For example, I use std::vector<strain>
elem_strain to store the strain tensor on gauss points. I understand that in
parallel, each processor own a part of this std::vector. In the final stage,
I want to use only processor 0 to write these value to a data file. How can
I do it?
By the way, does libmesh support the latest version of PETSC (v2.3.3 p8)
now?
Thank you very much.
