- To reproduce these simulations
-- Input UDF file: &ref(gravity.udf); &ref(gravity100000.udf);
-- Define UDF file: &ref(define.udf); [v3.02]
-- Command (remove "./" if you use Windows command prompt)
// > mkdir ./avs_g1
// > mkdir ./avs_g1/avs
> ./kapsel -Igravity.udf -Ooutput.udf -Ddefine.udf -Rrestart.udf
-- Visualization
--- You can make the same animation as above with &ref(particleshow_gravity.py); to be loaded from GOURMET. Open "output.udf"
