Coupling Error Between ANSYS Transient Structural and Fluent

Ayuba · March 12, 2014, 04:18

Hello all,
I hope you are all doing good and I wonder if any of would be kind enough to help me with this problem:

'the current flow time obtained from the fluent input file did not match the initial time obtained from the system coupling service'

I have coupled a transient structural system with CFD fluent and get the error above. I have also attached a clip of the problem. Thanks in advance for the much anticipated help.

Cheers
A.J

Have you tried to change the timestep settings in fluent to fixed and put in the value of timestep you choose for system coupling? I have always done it like that and never had that kind of problem. Also, did you make sure that your data transfer from fluent to structural is data transfer 2? I experieced problems when the number of data transfer from structural to fluent was not 1.
