For what it is worth:
With *KM.auxiliary_eqs*
one gets the forces acting on, say, the point where some multi body system
is attached to.
I tried to see, if one could also get the forces needed to make a particle
move in on predetermined path.
In the simple example attached (where the result is
Dear Jason,
I think my code is short, but I will have to ask my son how to attach a
file to gmail.
Thanks, Peter

Peter,
The ideal way to do this is to paste the code into the email or in a Github
discussion. Making the code as short as possible to demonstrate the issues
is also helpful.
Here is a good example: https://github.com/sympy/sympy/discussions/22848

Dear Jason,
Attached a Jupiter note book, in case this is better for you.
Thanks for any help!

Dear Jason,
I had to send it by separate mail, as I di not know how to attach a file to
gmail.😩😩😩
Thanks, Peter

You'll have to share your code for us to help, as this isn't enough

I try to model a simple one mass point pendulum in 3D, the mass point is
located on the y - axis, at a distance d. Rotations around the y-axis do
not make physical sense, hence, I use only qx, qz to describe the angles of
rotation of the frame of m.
If MM is the mass matrix, I get determinant(M
I was playing around with a simple 2D pedulum consisting of 4 bodies.
I included one non-holonomic constraint on one of the rotational speeds.
I also wanted to calculate the forces acting on the support of the

I calculated a very simple pendulum system, using one non - holonomic
constraint. All worked as per expectation. Then I tried to calculate the
reactive forces at the point of attachment, using KM.auxiliary_eqs. (KM
being the Kanes object).
