[petsc-users] Adaptive mesh refinement in Petsc

[Derek Gaston]

Miguel,

I'm the lead for the MOOSE Framework project Barry spoke of... we would
love to help you get up and running with adaptive finite elements for solid
mechanics with MOOSE.  If you are doing fairly normal solid mechanics using
small or large strain formulations with some plasticity... most of what you
need is already there.  You may need to plug in your particular material
model but that's about it.  Mesh adaptivity is built-in and should work out
of the box.  The major benefit of using MOOSE is that you can easily couple
in other physics (like heat conduction, chemistry and more) and of course
you have full access to all the power of PETSc.

I recommend going through the Getting Started material on
http://www.mooseframework.org to get set up... and go ahead and create
yourself a new Application using these instructions:
http://mooseframework.org/create-an-app/  .  That Application will already
have full access to our solid mechanics capabilities (as well as tons of
other stuff like heat conduction, chemistry, etc.).

After that - join up on the moose-users mailing list and you can get in
touch with everyone else doing solid mechanics with MOOSE who can point you
in the right direction depending on your particular application.

Let me know if you have any questions...

Derek
