[Mesa-users] Bug in diffusion?

[Aaron Dotter]

Hi Michael,

I've encountered this issue, too.

The use full net option will not generally work with OP monochromatic
opacities.  I presume you're using this to do radiative accelerations?

The OP data is only available for certain elements so you'll need to define
your own diffusion classes and map the elements in approx21 into the
elements available in OP "by hand".
