Hello All,

in an Model that I built myself I used the Driveline Worm-Gear Model with the MathWorks 3D-1D Interface (Link here).

Has anyone done so before?

I have no clue how to connect it properly.

It can´t compile when I add an Mechanical Reference due to Singularity Issues. It can Compile when I add an Inertia, but then the Simulation is Wrong.

I appreciate all help! Thank you!

Hello, is your problem already been solved? I am also trying to build a Simmechanics-Model for worm gear. Could you tell me what is the meaning of the worm base and worm follower and gear base and gear follower. Which part shouled be connected with worm, gear and frame?

I can't say for sure what your problem is because I can't see inside your interface blocks. But it seems to me you should be closing the loop of your fundamental rotational circuit around the worm gear. Have you tried connecting the R port of the right interface (revolute3) to your rotational reference?
