Node Distributing Technology for Parallel Computing of Spatial Truss Structure Using Vector Form Intrinsic Finite Element

Abstract:

After studying the computation rules in vector form intrinsic finite element(VFIFE) and the feature of spatial truss structure, a node distributing mechanism for parallel computing was proposed. According to the defined rules of decomposing, the model data of spatial truss structure were dynamically decomposed. Based on the results of decomposition, the data sets of nodes were dynamically decomposed, and the parallel computing was accomplished in the specific frame. The numerical experiments indicate that, the node distributing mechanism greatly improves the speed of spatial truss structure analysis, in contrast with those based on serial computing or classical finite element method.
