- To reproduce these simulations
-- Input UDF file: &ref(gravity.udf); &ref(gravity100000.udf);
-- Define UDF file: &ref(FrontPage/define_2.00.udf);
-- Command  (remove "./" if you use Windows command prompt)

    > mkdir ./avs_g1
    > mkdir ./avs_g1/avs
    > ./kapsel -Igravity.udf -Ooutput.udf -Ddefine_2.00.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"
