Name

gravidy - direct summation hermite N-body integrator with variable block timesteps

Synopsis

gravidy -i input_file ...

Description

gravidy is not installed by default in NEMO. See FILES below.

Example

Here is an example integrating gravidy with NEMO files 
  mkplummer p128 128
  snapprint p128 i,m,x,y,z,vx,vy,vz format=%.15f > p128.tab
  gravidy --input p128.tab --output p128 --interval 0.1 --time 10 --eta 0.01 --softening
0.05
  cat p128.out.snapshot_0* | sed ’s/# Time://’ | tabtos - - time skip,m,pos,vel
nbody=128 | csf - p128.out SnapShot
although note that the last snapshot (time=10.0) is replicated.
