Hi everyone,
I am solving fluid-structure interaction problem using Fluent, Mechanical and System Coupling. After calculation of a certain number of timesteps (over 800) and obtaining the maximum (20) coupling iterations, I cant get further - calculations are kind of stopped. In task manager, the ANSYS applications do not use any resources. I do not obtain any messages - contributing to license or convergence problems, which might cause such situation. Thus I dont have any idea why it is happening; I got typical outputs for succesfull calculations: in Mechanical - "Preparing the mathematical model" and in System Coupling Solution Informations - the convergence data for 20th coupling iteration (which are OK). I was waiting two days but nothing changed, then I restarted the computer and calculations and the problem appeared for the same timestep number. Please give me some suggestions how could I solve such situation Regards Destroy |

Is there any error messages or log files?
Do you mean the analysis shut down abnormally? |
