[mesa-users] Enabling diffusion in Mesa-r8118

[Émile Jetzer]

Thanks! I player around with different values of `diffusion_dt_limit`, & found that setting it to `1d3` works well. If I set the value too low, like 1 or 0, I have to start the simulation without the `do_element_diffusion` flag for the first few steps & then activite it & keep going with `./re`. Is there a known reason for this? MESA seemed to be concerned with the value of `log(dt/year)` which might be too close to 0 when `diffusion_dt_limit` is too small?
