I'm modeling atmospheric flow over a cubic obstacle with h2 dispersion (buoyancy on) behind the building. I'm runing a transient case. I'm having trouble fixing my model to correct the following messeges:
*** WARNING #009 ***THE VALUE OF SCALAR SC1 IN CELL 36 ( -6.7978-320) IS BELOW THE MINIMUM ( 0.0000E+00)
SCALAR VALUES BELOW THE ACCEPTALE MINIMUM FOUND AT *** CELLS •(after 100 time steps)
*** WARNING #013 *** MAXIMUM SPECIFIED CORRECTOR STAGES 20 REACHED BEFORE CONVERGENCE CRITERION IS SATISFIED.
-SCALAR EQUATION 1 NOT CONVERGE-
I suppose these are related. I have read all messeges that I could find on this problem... still not really clear on what to do.
For the scalar equation I'm using the CD (BF=1) 150 sweeps and 0.01 residual tolerance
Performed a grid check (tetrahedral) and the only prblems are a few angles (face) below limit
Avg Courant No. between 10-1
THANKS A LOT!
