What you are getting is simply a blowup, i.e. your current settings render the simulation numerically unstable. Some comments:

. If your case is transient use abstol for pressure instead of rtol. Say 1e-7 or lower. |

Hi,
I have been using the rheoTool toolbox to perform some DNS simulations of turbulent flow over a backwards-facing step, but my simulation is crashing, and I am ending up with a long error message that I am not sure what it is telling me.
rheoFoam error.txt
I am using a four-mode PTT-Linear Log model for my simulation (for blood flow). I can see from the log file that the iteration before it fails, the time step continuity errors get high, and it crashes.
Any help would be great.
