Abstract
Methods and systems for creating numerically-simulated rigid bodies in finite element analysis are disclosed. At least one rigid finite element in a finite element model is designated for forming one or more numerically-simulated rigid bodies (RBs). Each numerically-simulated RB comprises an arbitrary number of rigid finite elements connecting to one another in an arbitrary shape. Each numerically-simulated RB is created by locating all of the elements embedded in the FEA model through shared node or nodes. A procedure of using element definition as a guide to set up an array of node flags, each node flag for one node such that all numerically-simulated RBs defined in the model can be located efficiently. Once all numerically-simulated RBs have been located, each unique numerically-simulated RB is defined as a unique linked-list of connected rigid finite elements.
