Pellet Simulation (IMAGE) DOE/Idaho National Laboratory Caption A simulation of a fuel rod's pellets pressing against rod's protective cladding performed in MOOSE before (top) and after (bottom) implementing Coreform's spline technology. Contact is one of the most challenging physics to simulate, and in addition to being more accurate, the inherent ability to calculate smooth contact pressures makes these simulations easier to compute.
