Hi folks,
I am experiencing issues with a simulation in butterfly with two problems:
1) The simulation only runs for one time step and then stops, see below:
Create time
Create mesh for time = 0
SIMPLE: convergence criteria
field nut tolerance 0.0001
field k tolerance 0.0001
field U tolerance 0.0001
field p tolerance 0.0001
field epsilon tolerance 0.0001
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 RNGkEpsilon
bounding epsilon, min: -9.1400017 max: 4.1298733 average: 0.13855
RAS
{
RASModel RNGkEpsilon;
turbulence on;
printCoeffs on;
Cmu 0.0845;
C1 1.42;
C2 1.68;
C3 0;
sigmak 0.71942;
sigmaEps 0.71942;
eta0 4.38;
beta 0.012;
}
No MRF models present
No finite volume options present
Starting time loop
Time = 1
2) The snappyHexMesh tool fails to create a joined mesh, it seems just capturing the box alone.
You help would be greatly appreciated! Att: Rhino and gh file - thank you so much!
