Janek Kozicki posted a new comment: Yeah, CentralGravityEngine is a really bad name. I don't think it is used very often in yade so we could rename it to something like CentralAccelerationEngine. Then you could use that one as the basis for Newton's gravity and use distance as it should be used :) That would be a simple start for you. And easy to check - since you work with orbital mechanics, you should have simple examples at hand with starting acceleration and position to recreate the Earth-Moon system (or maybe even the solar system) to check this code. Basically your Newton's gravity Engine will be extremely similar to CentralGravityEngine (to be renamed into CentralAccelerationEngine) but you just need to add an extra line which uses distance instead of doing normalize on that vector :) After you make it work, you should have enough understanding to implement the Clohessy–Wiltshire equations. However you will need to learn a little about how to code C++. You can start by reading [1][2] and you are welcome to submit merge requests on gitlab, with your NewtonsGravityEngine and the Earth-Moon example [3][4]. This is a bit more work than you expected at first - I suppose that you wanted to write code in python only.
