About

MYSTRAN is a general purpose finite element analysis computer program for structures that can be modeled as linear (i.e. displacements, forces and stresses proportional to applied load). MYSTRAN is an acronym for "My Structural Analysis", to indicate it's usefulness in solving a wide variety of finite element analysis problems. For anyone familiar with the popular NASTRAN computer program developed by NASA (National Aeronautics and Space Administration) in the 1970's and popularized in several commercial versions since, the input to MYSTRAN will look quite familiar. Indeed, many structural analyses modeled for execution in NASTRAN will execute in MYSTRAN with little, or no, modification. MYSTRAN, however, is not NASTRAN. All of the finite element processing to obtain the global stiffness matrix (including the finite element matrix generation routines themselves), the reduction of the stiffness matrix to the solution set, as well as all of the input/output routines are written in independent, modern, Fortran 90/95 code.


PRIMARY AUTHOR: Dr. Bill Case was a member of the project management team for the development of the popular NASTRAN finite element analysis computer program developed in the late 1960's and early 1970's for the National Aeronautics and Space Administration (NASA). Over the course of 30 plus years from that time he was a structural analyst using NASTRAN and subsequently the head of an analysis branch comprised of approximately 20 analysts who used NASTRAN on many of the spaceflight structures built or managed by NASA Goddard Space Flight Center (GSFC). He has taught many graduate level courses in the area of static and dynamic structural analysis as well as basic and advanced courses in the use of NASTRAN. He is the author of many technical papers in the areas of finite element analyses and in the use of NASTRAN for major flight projects. From 2005 through 2011, Dr Bill Case was the president of MYSTRAN Software Inc (MSI) and developed and enhanced the MYSTRAN finite element analysis program to provide analysts with a cost effective solution for finite element analysis software. At the end of 2011 he dissolved MSI and is now providing MYSTRAN as a free tool for analysts to use. MYSTRAN is now a community project and Bill continues as a primary developer.
