Ansys 14 system coupling restart

Hello,
I'm simulating a transient coupled analysis of a fluid structure interaction using Ansys 14 with system coupling ( transient structural and fluent). my analysis requires very long runs, so I've written a script to stop the analysis, save and resume. This worked fine for the uncoupled analysis (it was performed earlier as a basis for comparison). I've set up the coupled analysis, and made sure it runs properly. But when the analysis is stopped and i try restarting it, an error occurs saying no *.ldhi file is found, and the restart is aborted. I've checked that my restart settings in the structural analysis are OK, and when running just the structural system the *.ldhi is there, and restarts are OK. can anyone help with this? |

Hello my friend,
I am trying to simulate fluid structure intraction like you (transient structure and fluent, using system coupling in workbench 14). actually, I generated msh file in gambit and then calculated fluid flow in the fluent seperately. subsequently, I drew the FSI in workbench and read mesh file for geometry, case/dat file for fluent. I actived dynamic mesh and select coupling system for walls, too. In transient structure, I read geometry and fluid-structure interaction is selected. As a result, can you introduce a toturial or explain the way that I should perform it? As you simulated FSI, you may have some toturials or files that be usefull for me. I do not have any idea for it Quote:
