Patent ID: 8145459

Claim:
A non-stochastic method of linking computer memory locations representing discrete particle tallies for computing particle transport, comprising: employing massive ray tracing for characterizing invariant geometric properties and relative particle distribution fractions in a field of voxel volumes, surfaces, and function coefficients producing predefined ray sets; overlaying material properties associated with a problem and traversing the fields within ray sets using ray set lengths and particle and wave source probability distributions to determine multipliers representing a fraction of particles transported from a reference discrete particle tally to neighboring discrete particle tally locations with a plurality of appropriate discrete variables; providing orderly specification of pointers to neighboring discrete particle tally locations related to invariant imbedding transport multipliers from a reference tally location; and sweeping through a system of reference particle tallies and corresponding multipliers to directly transport discrete particles to neighboring voxel volumes, surfaces, and function coefficients from an input initial condition.
