What is MYSTRAN?
MYSTRAN is a general-purpose finite element analysis computer program designed for structural analysis where displacements, forces, and stresses are proportional to applied loads. It is an acronym for "My Structural Analysis," reflecting its capability to solve a wide variety of finite element problems. The program is compatible with NASTRAN, a popular finite element analysis tool originally developed by NASA, allowing many structural analyses modeled for NASTRAN to run in MYSTRAN with minimal or no modifications.
Originally a commercial program, MYSTRAN is now a community project with ongoing development by a dedicated team. It features independent, modern Fortran 90/95 code for finite element processing, including global stiffness matrix generation and input/output routines. The tool is supported by documentation, Windows executables for end users, and source code available on GitHub, making it accessible for both users and developers.

FAQs
-
What is the primary purpose of MYSTRAN?
MYSTRAN is designed for general-purpose finite element analysis of linear structural problems, where displacements, forces, and stresses are proportional to applied loads. -
How does MYSTRAN compare to NASTRAN?
MYSTRAN is compatible with NASTRAN input files, allowing many NASTRAN models to run with little or no modification, but it uses independent, modern Fortran 90/95 code and is not the same program. -
Is MYSTRAN free to use?
Yes, MYSTRAN is a free, open-source community project with no cost for usage. -
What support is available for MYSTRAN users?
Support includes documentation, Windows executables, source code on GitHub, and community forums such as Discord for developers and end users. -
Who developed MYSTRAN?
MYSTRAN was primarily developed by Dr. Bill Case, with contributions from a community of developers, and is now maintained as a community project.
