Abstract :
We report on recent progress on the particle pushing component of the finite element gun code development program, MICHELLE. Two algorithms have been implemented. In the first algorithm, particles are pushed element by element through an unstructured grid, stopping at each element boundary. In the second algorithm, particles are pushed through smooth structured blocks of hexahedral elements. The structured algorithm is expected to be significantly faster than the unstructured algorithm, with some acceptable sacrifice in accuracy. Both algorithms employ a local coordinate system.
