I am modelling some mechanical part and performing a harmonic analysis. As boundary condition displacement is applied. The problem is, that I do not get any phase angle from the displacement. Also when using solid.uPhaseX the angle is always zero.

If your displacement boundary condition is +1[m] (for example) this is a phase angle of zero. If you wish a phase angle of 90 degrees you would write +j*1[m], etc.

To expand on Dave's answer: If there is any type of damping in the model, then the displacement will in general have nonzero phase angles, even when all loading has zero phase. Exactly at the driven boundary, the phase angle will match that of the prescribed displacement.

Thanks for the answer. The loading with zero phase is fine, the strange thing is, that the phase angle is 0 everywhere in the model
----solved now. I had no damping included!
Thank you!
