Dear all,

while sampling the Temperature my channel somthing strange comes up. The Temperature in the first cell almost equals the wall temperature. increasing the distance sensible temperaturedifferences are produced. This only happen when i use buoyantFoam ... using rhoTurbFoam this wont come up.

for completeness I post my sampleDict:

axis xyz;
start (10 0.5 0.49);
end (10 0.5 0.5);
nPoints 1000;

As i dont know how to post a picture I can't post the graph within the Tempreature distribution and the cellmidpoints ...

Hope you can help me..

Thanks Tobi
