We have a page on the wiki[1] that should list (scientific) papers mentioning SymPy, but it's currently empty. Populating this would be interesting and could also persuade other academics to try out/u…

A general nonlinear tire model takes the lateral slip angle, camber angle, and normal force as inputs and outputs the lateral force.
$$
F_y = f(\alpha, \gamma, F_z)
$$
If the tires are modeled…

Hello,
There are some problems with the testing using URDF model like iiwa14. The jacobian matrix has significantly error using symbolic method comparing with using iDytree and with geometricjacobia…

The math idea is as follows: I want to get frame 2 from frame 1, and then later substitute it to my equations to compute some cross products. (Here I present the simplified code.)
```math

For several applications users asked about sending global data, meaning data that is not associated to a mesh. Examples:
* Angles between coordinate systems (CAMRAD-CFD)
* Global background pressure…

We have a TaskSpace prototype class created by @chrisdembia and included along with the Simbody 3.5 examples (in the `examples/shared` directory). From that project we learned how the classes should b…

We had a long discussion in #16992. It turns out that pretty much every error discussed in that issue stems from the same source: someone added a zero inertia (mass and/or rotational inertia) body to …

Hi team,
I need to implement a simulation in which a 4-link manipulator captures a target body and then executes a maneuver.
For the pre-capture phase (in which the bodies are separated and indepen…
