    • In one embodiment, an apparatus includes a check/correct circuit coupled to a control circuit. The check/correct circuit is coupled to receive a block of data and corresponding check bits. The block of data is received as N transmissions, each transmission including M data bits and L check bits. The check/correct circuit is configured to detect one or more errors in each of a plurality of non-overlapping windows of K bits in the M data bits, responsive to the M data bits and the L check bits. The control circuit is configured to record which of the plurality of windows have had errors detected and, if a given window of the plurality of windows has had errors detected in each of the N transmissions of the block, the control circuit is configured to signal a device failure. Each of K, L, M, and N are integers greater than one.

    • Hybrid elements that enable coupling effects between SPH particles and FEM solid are disclosed. According to one aspect of the present invention, hybrid elements are configured to facilitate coupling effect of solid element based on finite element method (FEM) and one or more corresponding particles based on smoothed particle hydrodynamics (SPH). Hybrid elements are defined in a computer aided engineering (CAE) grid model as a buffer or interface between the SPH particles and FEM solids. For example, a portion of the grid model comprises SPH particles because the likelihood of enduring large deformation, while the rest of the model comprises FEM solid elements. Hybrid elements are placed between the solids and the particles. Each hybrid element comprises two layers: solid layer and particle layer.
