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 Flyspray task and see whether we have the resources to do it.

Kind regards
Bernd

Hi there
I continue my learning curve on Dumux..

(Kudos to the developer btw, the framework is relatively easy to grasp, well 
constructed and  I am finding answers to (almost) all my questions in the doc 
or the mailing list..
That said I have a question that allude me ( it has already been discussed in 
some ways but without a definitive answer I could identify tough).

Is there a simple way to visualize the fluxes variable, most importantly 
velocities, in a simplicial grid without heavy post processing...?

(I stumbled on the following message while porting the heatpipe lecture exemple 
 into a simplicial alugrid  Grid:
"ATTENTION: Velocity output only works for cubes and is set to false for 
simplice")

Thanks
JF
