Model disappears during forward simulation

[Cai Birch]

I've followed the tutorial of building the dynamic walker from the ground up, the model has functioned as predicted at each stage. I have now added coordinate limiting forces to the joints, compiled the code, debugged it and opened the model in OpenSim. The issue is that the model now disappears the moment I run it through a forward simulation. I'm not receiving any messages or indications why this is happening. Any ideas where I may be going wrong?

The properties for the coordinate limit forces are probably not set correctly. Take a peek at the solution here: https://github.com/opensim-org/opensim- ... 807c685a1e
