Question about transiet simulations in Fluent

Hello,
Could someone please clarify this for me.... When doing transient simulations in fluent, I set an adaptive time stepping technique (or constant time step, does not matter). I also specify the maximum number of iterations fluent can do in a single time step. It seems to me that if fluent did not reach a specified error threshold, it should either reduce the time step (if adaptive) and repeat Newton's method again, or just give an error (if constant time step) and stop the simulation. The user should then either ease the error threshold or manually reduce the time step. Yet, it seems that fluent does the amount of iterations I specified, accepts the solution even if the error threshold did not get reached and proceeds to the next time step. This means that my solution is junk because it's not within error! Someone please clarify this in case I am not understanding it correctly... Thank You! Vitaly |
