Today I was working on a (ModelingToolkit) problem with a single degree of freedom. But formulating everything with a single differential equation (plus supporting simple equations) turns out somewhat complicated / ugly. I’m pretty sure it has to involve root-finding. Mathematically, I’d really rath…

[image] cstjean: won’t one of my constraints (eg. conservation of energy) end up violated due to numerical imprecision? Yes, it will drift without being handled via an algebraic condition.
