Hello,
I am given the moments of inertia and deviation moments referring to
the global “AnyFixedRefFrame” co-ordinate system. Is there any
interpreter switch which tells AnyBody to refer these also to the
global co-ordinate system or do I have to transfer the tensors
manually to the local co-ordinate system?
Kind regards,
Hi Dieter,
You can use the JaboutCoMOnOff Switch to decide whether the inputted moments
of inertia
in Jii and Jij are related to the segment coordinate system (Off) or a
parallel system located
at the CoM (On). Please see the AnySeg section in the Reference Manual for
more info.
But I’m not absolutely sure if I got your question right.
Best regards,
Sebastian

Hi Sebastian,
thanks for the answer. Well, it depends on the initial situation:
Before I execute the “Set Initial Condition” operation all local
co-ordinate systems belonging to rigid bodies are overlapping on the
global AnyFixedRefFrame co-ordinate system. They are all parallel to
this co-ordinate system. But after the “Set Initial Condition”
operation they all rearrange. When are the moments of inertia and
deviation moments applied to the model?
Kind regards

Hi Dieter,
With the “Set Initial Conditions” operation the kinematics are solved for
the initial time step. Before this all segments are arranged according to
their defined r0 and Axes0 properties.
You can visualize the inertia properties with an AnyDrawSeg object. The
“potato view” will give you a good impression is everythings fine.
The inertia properties are part of the definition of the segment, so they
are there from the beginning.
Please ask again if this does not answer your question.
Best regards,
Sebastian
