So, newton DLL can be binded into EXE and nobody shouldn't know that it uses DLL newton ? But how about licensing..if we speak about commercial
projects?

Also, in which point do you think commercial physics engines are better than free engines ? for example what has Havok better than Newton ?

Also, do you know any fluid physics engines in pascal ?
or any algorithm about fluid or hydrodynamics...?
here is the dll inside exe project:

newton is one of rare free dynamic engines, which is also free for commercial use, but it is closed source, which should not be a problem imo, it has very free usage license.

havok, hmm.. no idea what could it have better, it might be faster, but i'd guess newton would beat it in precision, also, it is worth mentioning that newton is so stable, that it is using euler integrator internally (believe it or not), while other engines would explode if they used euler.

i am not aware of any fluid physics simulations done in pascal, newton however has fluid simulation.

if you are interested into pascal & pascal physics engines, you may want to check out MPL licensed PAPPE (PAscal Powerful Physics Engine):
