box2d for mechanical Engineers

Hello,

I'm trying to use box2d (porting for dellphi) for kinematic and dynamic simulations of linkages, and it looks very powerful and nice to use. I've to treat linkages smaller then 1 m, with bodies often smaller than 0.05m, and because of the limitation from 0.1 to 10 m, there are very big errors in collision and joint evaluation. Is there a way for increasing the precision of the calculation for small objects, also accepting a very slow evaluation process?

Any help will be apprecited.

I didn't find the right solution from the Internet.
