[FLASH-USERS] Laser driven biermann battery

[Aodhan McIlvenny]

Hi,

I've been hoping to implement the the extended MHD sections e.g. Biermann battery term into the laserslab example but having some issues with stability - it seems to require a very small tilmestep ( <1e-17s) which makes the implementation over a ~5e-9s window quite difficult. I have included my .par file in case anyone can help me spot anything I have overlooked or can give me any advice? The next goal would be to run this in a background magnetic field, which I have implemented, but the timestep required is <1e-20s.

The code was setup in 2D cartesian and +usm3t. I understand a number of papers have been written with Biermann battery and FLASH so naturally this was the first place to ask

Would appreciate any help

Best wishes,
Aodhan
