VAX to CRAY NASTRAN User Interface
Abstract
The Air Force Weapons Laboratory has access to both the NASTRAN and PATRAN software systems for structural analysis investigations; however, these two codes are resident on separate computer systems at AFWL. NASTRAN is used to perform the bulk of large structural analysis research and is resident on the CRAY1S. PATRAN is installed on Silicon Graphics and allows depictions and animation of modal analysis results. The two software packages are complementary in function, and communication between them can be achieved through the GATEWAY facility. The GATEWAY links the AFWLO4 VAX, the silicon Graphics IRIS, and the CRAY through a common network protocol. This document describes software residential on the VAX and CRAY computer systems which allows PATRAN animation of NASTRAN calculated modal shapes. This section contains general information which should be reviewed by all potential users. Section 2 outlines the step by step implementation of NASTRAN calculation and PATRAN animation. This approach is designated VAX/CRAY/VAX processing. The VAX/CRAY/VAX approach is appropriate regardless of whether the NASTRAN model was created on the Silicon Graphics using PATRAN or created on the VAX using an editor. Section 3 provides important notes on the use of the existing NASTRAN DMAP alter library, and Section 4 is an example computer session implementing VAX/CRAY/VAX processing as described in Section 2. Keywords: Computer communications.
