The recently imposed "must be logged in" restriction is a response to increased bot traffic on the site. This affects search, commits, and vuxml pages.
Search engines are not blocked. Try using "site:www.freshports.org" and your search terms.
After the ports freeze to fix some stuff, the freeze is over. I have some work to do before FreshPorts can start processing commits again before it can start processing again. I've created an issue for that.

Description:
NCrystal is a library and associated tools which enables calculations for Monte Carlo simulations of thermal neutrons in crystals and other materials, supporting a range of physics including both coherent, incoherent, elastic and inelastic scatterings in a wide range of materials, including crystal powders, mosaic single crystals, layered single crystals, amorphous solids, liquids, and gasses. Multiphase materials or isotopically enriched materials are supported as well, and the framework furthermore supports phase-contrast (SANS) physics.
