[Libmesh-devel] NewmarkSystem / LU - Solver

2008-07-11 Thread Mathias Nenning
Hello, I'm using the class NewmarkSystem. For solving the equation system I need to use a direct Solver. For this reason I start my programm like this: ./programm -pc_type lu The only drawback is that the Solver now calculates the LU-decomposition at every time step, as far as I know. But this

be compiled without error if I just derive from class "FEBase" - but that's not my intention... Is the compiler error due to the nested classes "Radial" and "Base" in class "InfFE"? I appreciate any suggestions - Thank's in advance... Mathias Ne

[Libmesh-devel] function pointer

2008-01-14 Thread Mathias Nenning
Hello! I'm programming a Newmarksystem... My question is, if it is possible to attach a "assemble function" which is a method of a class... Example: PoroNewmark { private: // declaration of a function pointer void (PoroNewmark::*funcP)( EquationSystems &es, const std::string& system_name ); p
