Thin Disk Galaxy Simulator

Intermediate User



Definitions of the various parameters used can be found here. Links to individual parameters are also available below.

Number of bodies to be integrated:  
-Note that larger numbers of bodies will take longer to simulate

Select the form of background potential to impose (look here for details):


The various forms of background potentials require variable inputs; see potential descriptions for specific use of each parameter for the selected potential:
param1:  
param2:  
-Note: The "Galaxy Potential" doesn't use these parameters

In addition to (or instead of) a background potential, the simulator can integrate using the self-gravity of the bodies (see here for details). Select the desired self-gravity integration method:


Choose the time duration of the simulation:  
-Note: Large values are allowed, but be aware that simulation time (and mpeg download time) will grow accordingly.

Enter the simulation timestep; ie, the time differential used to evolve particle trajectories:  

Enter the image dumping frequency; ie, the number of timesteps to elapse between movie frames:  

Select the dimensions in pixels of each MPEG frame:  
-Note: Larger MPEGs will take longer to produce and download.
