No converge solver massBuoyantBoussinesqSimpleFoam

First, I have to mention that I started a few weeks ago with OpenFOAM, so I'm not an expert in OpenFOAM. In order to be able to evaluate HVAC processes in a room, including humidity and heat transfer, I downloaded the massBuoyantBoussinesqSimpleFoam solver (see: http://openfoamwiki.net/index.php/Co...nesqSimpleFoam). To be able to run the tutorial of this solver in OpenFOAM 2.3.1, I adapted the following boundary conditions for group ".*" :
- For kappat: alphatJayatillekeWallFunction instead of kappatJayatillekeWallFunction; - For p_rgh: zeroGradient instead of buoyantPressure; Now, the solver runs without problems, but does not converge. Can somebody help me with this problem? For detailed information about the solving process, I attached the log file. Thanks in advance! |

Try refining the mesh because so far experience says that this seems to help. |

Hi I was wondering if you had any success with the current solver.
I am planning to use it myself for assessing humidity in interior spaces. I am not sure how it performs and how it's method can be considered proper. I was also wondering if anyone has been able to compile this for OpenFoam 3.0.1. Thanks in advance! Tellur. |
