How to set up transient one way coupling?

Hello everyone!
From the "Oscillating Plate with Two-Way Fluid-Structure Interaction" in CFX Tutorials and other documents, I found that generally for ANSYS packet(CFX and multi-field solvor) two way coupling calculation can be transient, but many cases for one way coupling are steady. I mean, like exporting the CFX result files and adding it to strucure in Workbench manually for each time step. How can I set up a transient one way coupling calculation using MFX which can be calculate for every time step automatically, or some other mehtod? I didn't find many statements about it in ANSYS help, just something about using "Additional Coupling Sent Data" for coupling wall boundary specification and setting the mesh motion to stationay in CFX Pre. Is that way OK? It seems to be OK, but I am not sure. Also, if to do so, is just single stagger iteration enough? Convergence criterion for stagger iteration is unmeaningful, right? Thank you~ |
