Hello,
i tried to solve the Optistruct OS-T 1600 Tutorial, but after starting the two solvers (optistruct, acusolve) there is a convergence error of acusolve that stops the job:
Messages for the job:
*** ERROR # 5202 ***
Acusolve stops before FSI iteration achieves convergence.
*** PROGRAM STOPPED: FATAL ERROR(s) ENCOUNTERED.
Does anyone knows the problem? I checked all steps of the tutorial and start it again, but the error still appears.
The next step was to change the convergence criterio of acusolve (convergence_tolerance) and optistruct (fsi card: FCNVTOL, DCNVTOL) and the exchange parameter of acusolve (min/max_stagger_iterations) and optistruct (min/maxEX), but the error still appears.
Does anyone has got experience with the tutorial OS-T 1600 and solved it successfull?
Thank you very much in advance.
