How to Couple AcuSolve & Optistruct for Fluid Structural Interaction (FSI)
Hi,
I have completed CFD simulation by using Altair AcuSolve for my model and by this have managed to analyze the fluid domain. currently I am trying to have single way coupling (FSI) from AcuSolve generated results with Optistruct for Structural domain analysis.
I've exported the results from AcuSolve in '.h3d' format and then imported it to SimLab. I've exported the solver deck '.fem' and then open it through hypermesh in order to apply all constraints and forces required for the mode.
I've saved the updated '.fem' and saved it.
I've then opened the Optistruct, allow in Co-simulation mode the 'FSI AcuSolve' ; added input file '.fem' and co-simulation file '.inp'.
the AcuSolve will be running but I had an error on the '.fem' file as per below:
* WARNING # 1284
No SPC or SUPORT1 data specified for static SUBCASE 1.
Make sure the model is constrained otherwise.
* ERROR 13: Element, 1 is repeated in the input data.

Element has repeat IDs 77963 time(s).
Is this due to wrong on exporting the solver deck ?
Appreciate help to know in coupling AcuSolve with Optistruct ?
