[ODE] Good reference for solving LCP's?

[Megan Fox]

Oh, of course.  I was answering the first bit of the question "how the
physics engine works" - without really knowing where he's starting.
If you can't solve the basic ODEs numerically, the joint constraints
will lack the necessary foundation.  I'm a big fan of starting at the
absolute foundation of a thing and moving up, rather than starting at
the top and working down - sorry for being unclear.
