<br style="font-size:14.666667px">
<span style="font-size:14.666667px">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. </span><br style="font-size:14.666667px">
<br style="font-size:14.666667px">
<span style="font-size:14.666667px">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</span><br style="font-size:14.666667px">
<br style="font-size:14.666667px">
<span style="font-size:14.666667px">Would appreciate any help </span><br style="font-size:14.666667px">
