| * | clusters/halo: Improve time step determination a bit | Aaron LI | 2017-10-19 | 1 | -1/+1 |
| | | |||||
| * | clusters/solver.py: Add FokkerPlanckTests with 3 cases | Aaron LI | 2017-10-12 | 1 | -9/+158 |
| | | | | | | | | | The FokkerPlanckSolver is validated with all the 3 test cases! References: * Park & Petrosian 1996, ApJS, 103, 255 * Donnert & Brunetti 2014, MNRAS, 443, 3564 | ||||
| * | clusters/solver.py: significantly improve fix_boundary() | Aaron LI | 2017-10-12 | 1 | -10/+30 |
| | | | | | Also suggest that ``buffer_np`` be specified to 5%-10% of ``x_np``. | ||||

| * | clusters/halo.py: Constrain tau_acc to avoid zero diffusion | Aaron LI | 2017-07-23 | 1 | -0/+7 |
| | | | | | | | | | | | Zero or negative diffusion coefficient leads to unstable or wrong results due to numerical algorithm/scheme adopted to solve the Fokker-Planck equation. Also add a NOTE to the FokkerPlanckSolver class. Signed-off-by: Aaron LI <aly@aaronly.me> | ||||
| * | clusters/solver.py: Improve documents and clean up | Aaron LI | 2017-07-22 | 1 | -14/+49 |
| | | | | | | | | | TODO: adaptively determine the proper time step instead of using a constant one. Signed-off-by: Aaron LI <aly@aaronly.me> | ||||

| | | | | | | | | To avoid the too small (or zero) values for the diffusion coefficient of the Fokker-Planck equation. Also change config "extragalactic/halo/pmax" from 1e4 to 1e5 | ||||
