Hello,
i am comparing results for an HVAC system with different meshes(timmer and poly).with trimmer mesh the results are quite acceptable. on the otherside, i am not changing anything, like mesh settings, boundary conditions etc. coming to the results i am seeing a drastic fall in the data (avg. velocities, avg. pressure, mass flow rate etc.) collected for poly mesh. can anyone share ideologies what can possibly go wrong?

Hi Bharatt, you probably have a strong gradient (in velocity?) and your polyhedral mesh is not capturing it?
What part of the HVAC system are you modelling? Best regards, Guillaume TrampoCFD.com |
