Running the Simulation
You run the unsteady simulation for a physical time of 0.2 s, with a time-step size of 0.0005 s.
To aid solution convergence, modify the under-relaxation factors for the solvers, and set the Phase Slip Velocity solver Body force smoothing iterations to 2.
To run the simulation:
-
Edit the Solvers node and set the following properties:
Node Property Setting Implicit Unsteady Time-Step 5.0E-4 s Under-Relaxation Factor 0.6 K-Epsilon Turbulence Under-Relaxation Factor 0.3 K-Epsilon Turbulent Viscosity Under-Relaxation Factor 0.3 Phase Slip Velocity Body force smoothing iterations 2 -
Edit the Stopping Criteria node and set the following
properties:
Node Property Setting Maximum Inner Iterations Enabled Activated Maximum Inner Iterations 25 Maximum Physical Time Enabled Activated Maximum Physical Time 0.2 s Maximum Steps Enabled Deactivated Stop File Enabled Deactivated Stop Inner Iterations Deactivated -

(Run) in the Solution toolbar.
- When the simulation has finished running, save it.
