Hi, I am doing unsteady calculation with LES turbulence model. From the fluent guid, I saw that the residual should reduce 3 order within each time step or reduce as the flat. I am not really clear about that.
1. Do we need to set critical convergent in monitor panel for transient calculation or change it to none?
2. Does residual effect the sulution?
3. This is the residual of my calculation. Is this ok?

Thank you!
