COMMON ENVELOPE SIMULATIONS

Update 4/29

Radiation Pressure Paper

Moving this to the top of my to-do list. Should have first final look done in next couple of days.

Charge Exchange

A few more Stampede problems. Made it up to line transfer step with last run, so I'm hopeful it will just run now.

AMR line transfer

First clump test (radiation pressure only) still partially successful (See code page, though I have a few more frames). Local ray communication works, and fixed race condition (though still may switch to buffered sends). Currently tracking down source of unmatched sends and/or receives.

COMMON ENVELOPE SIMULATIONS

Update 4/18

Charge Exchange

Square appears to be from a combination of diffusion and advection (advective ionization is significantly negative). Chombo conversion appears essentially correct (slight discrepancies between max and min of rho?), so attempting to run on stampede.

AMR line transfer

First clump test (radiation pressure only) partially successful (See code page. I'm running into what appears to be a race condition in the MPI library - multiple recvs are being used to accept the same sends. I've put debugging this on hold while developing the local (non-MPI) communication.

Currently testing the MPI-less implementation.
