Hi Mohammad,

you don’t need to delete any build files or make changes to dune for such 
changes. Dumux is currently header-only so all you need to do is to recompile 
your executable.
You most likely changed something in a wrong file/function. Make sure the 
function you changed is actually called by putting some output in there.

Apart from that I’m not sure why you get to this region. With T=980K, 
p=9.91e+06Pa you probably shouldn’t have liquid water, right?
So maybe the actual problem is really somewhere else?

Timo
