Hi,
I am trying to run a simpleFoam model but I am getting a no MRF models present, what could be causing this? The finite volume options present error can be solved by adding a fvoptions file. Also how do you set the convergence criteria? Any help would be great Create time Create mesh for time = 0 SIMPLE: no convergence criteria found. Calculations will run for 500 steps. Reading field p Reading field U Reading/calculating face flux field phi Selecting incompressible transport model Newtonian Selecting turbulence model type RAS Selecting RAS turbulence model kOmegaSST Selecting patchDistMethod meshWave bounding k, min: 0 max: 0 average: 0 bounding omega, min: 0 max: 0 average: 0 RAS { RASModel kOmegaSST; turbulence on; printCoeffs on; alphaK1 0.85; alphaK2 1; alphaOmega1 0.5; alphaOmega2 0.856; gamma1 0.555556; gamma2 0.44; beta1 0.075; beta2 0.0828; betaStar 0.09; a1 0.31; b1 1; c1 10; F3 false; decayControl false; kInf 0; omegaInf 0; } No MRF models present No finite volume options present |

I managed to solve the finite volume issue, but now the solver just stops?
