hi, dear foamers,
I am on 1.5-dev. And I am trying for LRR, but unsucessful. --------------------------------------------------------- Create time Create mesh, no clear-out for time = 9.5e-05 Reading field p Reading field U Reading/calculating face flux field phi Selecting incompressible transport model Newtonian Selecting LES turbulence model LRRDiffStress LRRDiffStressCoeffs { ce 1.05; ck 0.09; c1 1.8; c2 0.6; couplingFactor 0; } Starting time loop Time = 9.51e-05 Courant Number mean: 7.64659e-05 max: 0.00441883 velocity magnitude: 6.35951 Floating point exception .................................................. ..................... I have tried to use the DeardorffDiffStress as a start up, then change to LRR, but stil this problem. Can you give me some hints for this? thanks in advance. |
