_re: I would be interested knowing if there is a way to do this without sampling the gammas._ Can't we use Gamma-Ray Dose Constants to do that? (been thinking about...

I've create an 'issue' feature request for this I think you can change the distance and mass, just need data on air attenuation. > > _re: I would be interested...

perhaps the wrong words. I am creating a regular mesh `openmc.RegularMesh()`, using it as the domains. `get_microxs_and_flux` is ignoring it and using the existing mesh of the weight window

I'll look to draw up an example when I can, it's hard as there are many moving parts with prop data This was using wws=from_xml (so as XML) At large,...

Yes, I am aware. 100 statepoints in my run directory, that need to be cleaned up at the end of calculation is messy and not very practical. Some sps get...

Thanks, I like the use of -1. That's a common thing elsewhere, though I don't think in OpenMC we do that too much (I'm quite happy with such a toggle)....
