Dear Solver-Experts,
I am running a case in rhoSimpleFoam and I get exploding values for temperature and especially density after few iterations, but no divergence. This even happens for turbulence turned off. I have to blame a few cells in my prism layer (low-Re, layer next to wall) for this. I am trying to bound rho and h in some way, but without success so far. I tried: Code:
interpolationSchemes { interpolate(rho) limitedLimitedLinear phi 1.0 1.0 1.25; ... } Regards Last edited by bastil; February 17, 2010 at 10:59. |

fixedValue, 1e-20 for k and epsilon (for LaunderSharma-k-epsilon) zeroGradient for temperature I am not sure for temperature... The only similar tutorial case is NacaAirfoil from turbFoam. This uses zeroGradient for temperature but also for k and epsilon which is obviously wrong? Any other ideas? Thanks. Regards BastiL |
