Re: [Libmesh-users] parallel mesh/mesh partitioners

By default if you just use the examples exactly the way they are it will just work the way you expect it to. Don't worry about partitioners and mesh classes until you _know_ you need to. Basically, with the default configuration the mesh will be read and partitioned automatically. Derek Sent fr

[Libmesh-users] parallel mesh/mesh partitioners

2011-11-07 Thread Ataollah Mesgarnejad
Dear all, I'm somewhat confused by parallel mesh and mesh partitioner class (and it's sub classes: ParmetisPartirioner, MetisPartitioner,…). I wonder if someone can explain steps you need to take after reading a mesh file on head node (or constructing mesh) to partiion it (say using parmetis)

[Libmesh-users] boundary conditions without penalty in DifferentiableSystem

2011-11-07 Thread Matteo Semplice
Dear all, I am afraid that boundary conditions imposed with the penalty method are confusing NewtonSolver for a nonlinear system of PDE's I'm working with (I have already checked the jacobians with verify_analitic_jacobians...). Thus, I would like to rule out the penalty method as culprit
