Why do calculations blow up when using finer grids (k-omega SST)?

http://jimhawley.ca/downloads/Plotting_OpenFoam_residuals_and_forces_in_real_time.pdf WebThe second one is to use the PIMPLE algorithm in the correct way. The PIMPLE algorithm combines the PISO with the SIMPLE. That means, the problem is transient but we use the SIMPLE (steady-state) treatment to find the steady-state solution for each time step. This allows us to increase the Courant number larger than one. the church teaches forumWebMy solution is crashing early in the solution with "bounding epsilon" and I can't figure out why. I have a feeling that the problem is with my pressure BCs. Using tutorials as reference, I set only the fixed value as 100kPa for the outlet in the p_rgh field with other patches and walls as fixedFluxPressure. the church sugarbush

"WebThe sparger pumps air into the mixer at -0.00103745 m/s and the gas leaves the micro-bioreactor from the outlet. I got bounding epsilonm as shown below, sometimes bounding km.
