Basic Question on Convergence
Hello
I am studying chaotic mixing in microchannels. My model is 200 microns wide, 100 microns high, and 1500 microns long. My velocity is 2 cm/s. I used a hexahedral submap mesh with a spacing of 5 microns to give me 256000 cells. I am looking at just velocity fields, and then applying a UDS species. I want to converge my flow to a level that is appropriate. How do I determine this? My residual plots keep decreasing. Are they supposed to level out? I've done 700 iterations and it gets to 1e-8 and is still decreasing. Do I need more iterations? What timestep should I be using? How do I input that? thanks very much. I am new. anshul |
Re: Basic Question on Convergence
Hi. You can create a surface plot where you can monitor values of say temperature in a point or a surface. That might help you to determine if your case has converged.
