Hi Christoph, Thank you for your quick answer. I was wondering whether I could use the functions in eigenvalues.hh. Is this not a good idea?

Dune-ISTL has some eigenvalue computation support. I'd advice you to hack the DuMuX assembler and print everything into a Matlab/Octave file. Using their capabilities it's easy to obtain the eigenvalues. - you can get the matrix for example in dumux/implicit/common/implicitassembler.hh at the end of the assemble() method - use dune-istl's Dune::writeMatrixToMatlab Bye Christoph -- ... as Sir Cyril Hinshelwood has observed ...fluid dynamicists were divided into hydraulic engineers who observed things that could not be explained and mathematicians who explained things that could not be observed. -- James Lighthill ********************************************* CMWR 2014: 10th - 13th June 2014 in Stuttgart Please visit www.cmwr14.de ********************************************* _______________________________________________ Dumux mailing list [email protected] https://listserv.uni-stuttgart.de/mailman/listinfo/dumux
