Caution

Please do not edit this file (page) manually since the workflow will overwrite your changes.

This file (page) is automatically generated by the workflow Update test problem wiki page using the script tool/wiki/sync_test_problem_pages.py.

Default setup

None

Note

• Test the evolution of the Plummer model

  • Plummer_Collision = 0: test the stability of a single Plummer cloud 1: test the collision of two Plummer clouds

• One can set --passive=2 and Plummer_AddColor=1 for Plummer_Collision=1

  • Different clouds will be assigned with different passive scalars

• Plummer cloud(s) can have both gas and particles

  • Plummer_GasMFrac: gas mass fraction

• To enable feedback

  1. Enable FB_USER
  2. Enable Plummer_FB_Exp and/or Plummer_FB_Acc

• To test mass conservation to the machine precision with mass accretion feedback

  1. Set Plummer_FB_ExpMMax=0.0 (no mass loss in explosion feedback)
  2. Set OPT__BC_FLU_*=1 (periodic BC)
  3. Use the gnuplot script plot_script/plot_mass.gpt
