How to couple optistruct with Acusolve?

Rahul_P1

Hi all,
I am thinking about using Optistruct and Acusolve together to optimize the composite layup of a front wing of a race car. My problem is that I am not clear about how to extract fluid simulation result of Acusolve and apply it as boundary condition of the structural optimization in Optistruct. I have watched demos regarding practical fluid structure interaction between radioss and Acusolve but unfortunately, this part is not covered in the official demo. Does anyone have any suggestion?

Thank you!

It depends on which boundary condition you need extracted and used in the optistruct analysis.

If it is pressure for instance, you can easily extract a txt file from acusolve results with the pressure value for each node, use HyperMesh linear interpolation option to use the same text file to apply pressures on the nodes while pre processing for Optistruct and you have hence coupled Acusolve and optistruct.
