[ODE] Large mass and accuracy

The examples I built so far showed that masses like 2000 kg are no problem
if you adjust some parameters (ERP, CFM, collision params), but I still had
problems with masses of around 50,000 kg (e.g. a large truck or a tank),
for example the wheel joints behaved strangely. Would be nice to get some
feedback from someone who has experience with this topic.

Hello all!

When I ahve large mass values (e.g. 2000 for a car).
Could such large values cause numeric drift and instability, when used
in an ODE simulation?

thx!
