Preconditioner and Linear Solver

Hi, I am interested in parallel iterative methods for solving linear systems. Specifically, the preconditioners in Domain Decomposition Methods. What is the correct path I should take if I want to implement a preconditioner other than the ones provided by ElmerSolver ,for example, Neumann-Neumann pr...

VTK and VTU

Hi all,

When I print the results as VTU format I get huge numbers something like infinity !!! though if I use VTK format the results are OK. Any idea why I am getting different outputs when I change the format ?
