Error control wants to select step smaller than minimum allowed

Question

I'm getting the following error when I run my simulation

terminate called after throwing an instance of 'std::runtime_error'
  what():  Error control wants to select step smaller than minimum allowed (1e-14)

Answer 1

Copying Russ's answer from piazza here

you probably have something in your dynamics that is returning inf? (which means the simulator is trying to obtain an impossible accuracy).

you can put the simulator into fixed step mode to power through, but you'll just be simulating nonsense. i think you need to find the source of the numerical blow-up.
