I have a problem with Resistance under CFD 2014.
I have CFD Study which was created, simulated and post-processed with CFD2013.
Now i use the support File for import in CFD 2014, because i need the geometry in 2014.
But it do not work. 2014 have any problems with the Resistance. Any cases divergence...
i pick for the resistance a konstant value of 20 in the main flow. The secondary flow is locked by me with a value of 1e+6 and 1e+7 (like in the tutorial and handbook).
I think, the solver have problems with the high resistance constant value.
Do you have any ideas?
Solved! Go to Solution.
Probably, your turbulence numerics is not relaxed approproately? How about decreasing the under relaxation factors? Also, you may want to make sure Automatic Intelligent Control is enabled, it takes care of timescales through out the domain. You can only judge the performance of resistance after you are sure all the other factors are taken care of.
