1-Way FSI-Transient-Time Stepping
 

Hi,
I am doing my masters project on FSI of microturbine to evaluate stress on blades.. I have completed CFD Part in Fluent. Also linked the result to Transient Structural as Workbench Procedure. I have successfully imported pressure on blades. Also given equivalent time steps as i given in transient fluid analysis previously.. But still its not matching in Analysis Settings..
I have also kept node-to-node connectivity btw solid and fluid( am not sure whether its required or not).
180k elements-tet. 720 time steps each of 3.33e-6s
What might ve went wrong,, whether its bcs of tiny time step?

( i am able to get results for steady state CFD and Static Structural Analysis bt its not working with transient, also am unable to import transient CFD results as Static Load in Static Structural)

kindly looking for help..
Thanks in Advance

There's no automated mapping between transient CFD and transient structural. Two options:
1. Use the External Data component (export CFD results to ASCII files, then follow the documented External Data procedure for importing multiple files)
2. Take a look at "FSI Transient_R145_v1" on https://support.ansys.com/AnsysCusto...ry/ACT+Library

i do not have a user name and password for customer portal.

is it possible to upload one of the tutorials about coupling transient structural and fluent?
