Gmsh is getting better for me every day! Too bad dolfyn does not 
have this particular feature YET...

The status on the interface: everything works well but the dolfyn 
preprocessor needs to be adapted/changed. Up until now the solver 
did not care about the order of the boundaries ('physical 
surfaces') in order to feed back the results the order needs to be 
the same (especially since I'm thrilled by Jean-Francois Remacle's 
madlib).

I noticed that the (named) 'physical surfaces' allways come first 
and then the 'physical volumes'. That means that once the boundary 
order is retained no maps are necessary. This even should work if 
the 'physical surfaces' and 'physical volumes' are mixed.

Only one tiny remark: MAdLib will only work for tetrahedral or 
triangular meshes (according to the site). In the CFD world one 
loves, well needs, to use prisms along (important) walls. So a hint 
on the future development?

Thanks guys! Happy Easter!
