RVO Simulator incompressibility

I saw incompressibility mentioned in a couple older posts, and in screenshots, and I see it is still in the documentation for RVOSimulator however I cant find it in the RVOSimulator script. Is this no longer there?
If so is there an equivalent?

Hi

What version are you using?
If you are using the latest beta version, then no, it has been removed because the underlaying algorithm changed and it became unnecessary.
