Timestep-Control (Subroutine)

Hi,
I have a problem with timestep control in user-fortran Subroutines! My task is to write a subroutine for the fluid-structure-interaction (FSI) without using the given MPCCI code. Now I planned to write a routine, which is called at the end of each timestep and check the convergence of the calculated solution. If the convergence is OK, the simulation keeps on going and the next timestep is calculated. But if the convergence is bad, the solver should jump to the end of the timestep before and repeat calculating the actual timestep. Therefore I will have to manipulate the solver-stack and I need more informations about the solver data-structure! So here are my questions to specialists in CFX: 1. Where can I find detailed informations about the solver data-structure? 2. Which data has to be manipulated, to set the solver to the end of a before calculated timestep? (f.e. copy /FLOW/SOLUTION/LATEST to /FLOW/SOLUTION/TSTEPn/CLOOPm, or setting ATSTEP to a special value) Thanks for any reply, Gabor |
