[DuMuX] Interest in User Meeting?

2014-12-02 Thread Bernd Flemisch
Dear Dumux users, it seems to me that enough people outside of our Stuttgart working group could be interested in a Dumux user meeting. I can think of ~2 days here in Stuttgart in late spring / early summer, which we could divide in presentations by the users and hands-on problem-solving/-crea

Re: [DuMuX] Is it possible to extract the velocities and other flux vatriables with a simplical grid ?

2014-12-02 Thread Bernd Flemisch
Hi Jean-Francois, the velocities are calculated in dumux/implicit/common/implicitvelocityoutput.hh. As the message says, the implementation assumes at a few lines that one has quadrilaterals/hexahedrons. At a first glance, it does not seem to be very difficult to generalize. I will open a Fly

Hi Hai, implementing another time discretization will be a non-trivial task. For the implicit models, the implicit Euler method is hardcoded in dumux/implicit/common/implicitlocalresidual.hh. In the routine evalVolumeTerms_, the time derivative is set to the first-order finite difference and
