One Way FSI Coupling

ashtonJ · December 3, 2014, 03:03

Dear all,
I want to do transient one-Way FSI using 2-Way FSI framework; however, I have no idea how to specify in CFX to not send back displacement to the CFX.
I would be too pleased if any body could help me.

Thanks
AshtonJ

Hi,
I don't know if this can help, but I have seen a 1-way fsi calculation in the webinar from the 23th september.
i think you have to download some ACT extension librairy for a FSI transient calculation.

After that you settle your mechanical box with the data from CFX in Workbench: share the geometry and transfer the solution of CFX to the setup of mechanical.

Hoping this will, but for something this particular, I think that the support from ANSYS will be more precise than me.

Regards,

If you want to use the 2-way framework for this then set the CFX boundary condition as stationary and use the "Additional Coupling Sent Data" section on the boundary condition panel to send the forces.
