BOPACE 3-D (ADDENDUM) (The Boeing Plastic Analysis Capability for 3-Dimensional Solids Using Isoperametric Finite Elements)

摘要

This addendum to the BOPACE 3-D (Boeing Plastic Analyses Capability for 3-Dimensional solids using isoperimetric finite elements) Program document (Rsf. 1), describes modifications and additions incorporated into the program version dated September 1975. These include the following major items.n1. Restructuring of the program to allow solutions of certain 3000-DOF problems within 64K words of core. (This also increases the allowable equation bandwidth/wavefront for larder core storage allocations).n2. Generalization of the isoperimetric element library, which now allows use of an element with any number of total nodes from 8 to 44, with any individual edge having from 2 to 5 nodes arbitrarily snaked along its length.
