Title: simulation in rotating system
Post by FedericoP on 03/22/12 at 10:46:20

Hi everybody,

I try to simulate the orbits of a ring of particles in the rotating system. I would like to show something like the horsehoe orbit seeing in the simulation above (from gravity simulator simulation page!) BUT with 20 or more particles so i can see the differences between the orbits of the particles.


Could someone help me to find the correct initial condition for the test particles?  :'(  :'(

THANKS A LOT GUYS !  :D

You need to have one massive particle in the system or the horseshoe will not work.

Try this:
File > New  (this creates a simulation with only the Sun)
Objects > Create Objects
create an object at 1 AU with a mass of 1 Jupiter mass.  Leave all other values at their defaults.
Objects > Create Objects
create 20 objects at 1 AU.  Set their Mean Anomoly to 180 +-100%.  Leave all other values at their defaults.
Set the rotating frame rate to the planet's period using View > Rotating Frame Adjustment and choosing the planet from the dropdown list.
