In order to check the derivative-approximation a simple possibility is to just integrate it and see that it is roughly the same as the original. It doesn't replace the reference...
The current description of UnitDelay has two issues: - It is plain wrong regarding "second" - It doesn't document the strong restriction that UnitDelay only works for sampled inputs, this...
The model has the comment "Use this model if the pump characteristics is of secondary interest." However, even if the values for the pump characteristic as default has zero impact...
Modelica.Mechanics.MultiBody.Joints.SphericalSpherical and Modelica.Mechanics.MultiBody.Joints.UniversalSpherical contain formulas of the kind: ``` if kinematicConstraint then rRod_0 = transpose(frame_b.R.T)*(frame_b.R.T*frame_b.r_0) - transpose( frame_a.R.T)*(frame_a.R.T*frame_a.r_0); else rRod_0 = frame_b.r_0 - frame_a.r_0; end if; ``` To me this...
