My understanding was that once I define a material (226Ra in my case), this new material should show up in LOW-MAT pull-down menu’s both WHATs (i.e. Mat: and LowMat:), however, I can only see it in the Mat field and not in the LowMat, which results in an error if I run the simulations. Is this a bug?
Also, as I am trying to simulate the yields from a 226Ra target bombarded by 20 MeV protons, I think, I don’t really need the LOW-MAT card. But if I disable the card, I still get error. Is this another bug?
I am using the latest FLAIR 3.0-5 and FLUKA-2011-3.0.Linux-gfor7 on Ubuntu 18.04.
Can someone please comment what might be the problem?
