  • Computer process for prescribing second-order tetrahedral elements during deformation simulation in the design analysis of structures
    Patent number: 6044210
    Abstract: A computer implemented process prescribes second-order tetrahedral elements during simulation in the design analysis of structure. The computer implemented process includes the steps of defining a finite element model for an element including at least one tetrahedral element, and defining the at least one tetrahedral element as a combination of hexahedral sub-elements. The computer implemented process also includes the steps of executing the simulation, and evaluating the structure for structural integrity responsive thereto.
