POESSY, A Computer Program for the Automatic Generation of Reentry Vehicle Nose Tip Finite Element Models.
Abstract
The theoretical background of the automatic nose tip finite element model generator, POESSY, is described. The POESSY computer program consists of four basic subprograms which perform different distinct steps in the automatic generation and translation of nose tip models. They are PGMESH which automatically generates the structural finite element mesh, PGPRES which translates the surface pressures and temperatures, PGTEMP which translates the indepth 2-dimensional temperature field and PGPLOT which plots the resultant finite element mesh and temperature contours. The POESSY code is designed to accept the output data from a thermochemical ablation, shape change, in-depth temperature response computer code and prepare it for input to a thermostructural analysis computer code with a minimum amount of effort by the user. The use of the POESSY computer program is demonstrated by sample problems solved for a typical plug and shell nose tip. (Author)
