CFX residual bouncing
1 Attachment(s)
Hi, i'm doing the simulation of the spray with water mist. Initally i'm using mass flow rate of 2g/s of injected water mist, the solver is steady and converge, When i increase the mass flow rate of the injected water mist to 200g/s, I'm facing the convergence issue and the residual is bouncing as shown in the attachment. May i know how can i resolve this issue? Any one can help me? Thanks.

i think with decreasing time scale.

Hi, thanks for your reply. Currently, i'm using auto time scale, should i change to physical time scale, and use small time step?
Thanks. |
