Abstract

A physical process is simulated by storing in a memory state vectors for voxels. The state vectors include entries that correspond to particular momentum states of possible momentum states at a voxel. Iinteraction operations are performed on the state vectors. The interaction operations model interactions between elements of different momentum states. For a particular state vector, the interaction operations include performing energy-exchanging interaction operations that model interactions between elements of different momentum states that represent different energy levels. A rate factor for the voxel represented by the particular state vector affects a degree to which energy-exchanging interaction operations cause a transfer of elements from states representing lower energy levels to states representing higher energy levels, rather than from states representing higher energy levels to states representing lower energy levels. Move operations then are performed on the state vectors to reflect movement of elements to new voxels. The rate factor is generated for a voxel based on rate factors for voxels from which elements of the voxel moved.
