MYSTRAN
=======

MYSTRAN is an acronym for “My Structural Analysis” (https://www.mystran.com)

# Build Instructions

See [BUILD.md](BUILD.md) for both Windows and Linux build (compiling) instructions.

# Introduction

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 its 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. Many structural analyses modeled for execution in NASTRAN will
execute in MYSTRAN with little, or no, modification. MYSTRAN, however, is not
NASTRAN. It is an independent program written in modern Fortran 95.

# Features

- Nastran compatibility
- Linear Static Analysis
- Modal analysis
- Linear Elastic Buckling Analysis
- Full Suite of 1D, 2D, and 3D elements
- Support for Classical Laminated Plate Theory
- OP2 Supports

# Get EXE or Make Binary

Windows EXE (executable) for can be found in the "Releases" section of this page (right hand pane).

Static Linux binaries have been built, but releases are in work.
For now, it is better to build it yourself -- it's really
straightforward.

# Documentation

The end user documentation is located the [MYSTRAN_Documentation](https://github.com/MYSTRANsolver/MYSTRAN_Documentation) repository.
This includes a Quick Setup Guide, User Manual, and Theory Manual.

# Five Repositories

The MYSTRAN project consists of five repositories.

1 - This repository contains the source code and build instructions.

2 - The [MYSTRAN_Documentation](https://github.com/MYSTRANsolver/MYSTRAN_Documentation) repository contains various documents related to the MYSTRAN program.

3 - The [MYSTRAN_Resources](https://github.com/MYSTRANsolver/MYSTRAN_Resources) repository consists of files for MYSTRAN developers.
It also contains information and files related to pre- and post-processors relevant to MYSTRAN.

4 - The [MYSTRAN_Validation](https://github.com/MystranSolver/MYSTRAN_Validation) repository contains models with verified results and code to automatically check a MYSTRAN binary against the expected results; this keeps track of our validation effort and prevents regressions.

5 - The [MYSTRAN_Benchmark](https://github.com/MYSTRANsolver/MYSTRAN_Benchmark) repository contains the original test cases and some utilities used to verify results before the Validation repository started.

# Developmental Goals

- Continue the implementation of the MITC shell elements and shell element buckling capability
- Validation effort (hundreds/thousands of test cases)
- Discover and resolve bugs
- Improve performance

# Ways You Can Help

- Join the MYSTRAN Discord Channel and/or Forum (links below)
- Report bugs and inconsistencies
- Report issues with Documentation
- A large validation  effort is underway. This will require the assistance of the community. Any help would be greatly appreciated.
