Frequency response analyisis Delay

Toon

I am trying to simulate the influence of an unbalanced tyre on the structure using an FRF. Because it is rotating in the XZ-plane I have made two inputs, one excitation in X and one in Z. I combine these inputs in a DLOAD through 2 RLOAD load collectors. The thing I am struggling with is implying a 90 degree phase delay for one of the 2 RLOAD collectors. I have expirimented with the delay option and dphase option but I have not obtained the result I wanted. How do I apply this delay in my model? Is there a tutorial for this?

Which version of OptiStruct you are using? Could you please share the .out file of the run.
