Linear finite element analysis with MYSTRAN

MYSTRAN is a software designed for linear finite element analysis of structures. It is an acronym for “My Structural Analysis,” indicating its versatility in solving various finite element analysis problems. The input format for MYSTRAN is similar to the popular NASTRAN program developed by NASA in the 1970s, and many structural analyses modeled for execution in NASTRAN can be executed in MYSTRAN with little or no modification.

However, MYSTRAN is not NASTRAN, as all the finite element processing, including the generation of the global stiffness matrix and the input/output routines, is written in independent, modern Fortran 90/95 code.

What is linear finite element analysis?

It is a numerical method used to approximate the solution of partial differential equations by dividing the domain into smaller elements and approximating the solution within each element using a linear function.

It works by dividing the structure into smaller, finite elements, which are interconnected at specific points called nodes. These elements and nodes form a mesh that represents the structure.

In linear FE analysis, the stiffness matrix is computed by assembling the element stiffness matrices.

The element stiffness matrix represents the relationship between the forces and displacements within an individual finite element. It is derived from the material properties, geometry, and shape functions of the element.


What are the advantages of using open source software for solving linear FE problems?

Open source software for solving linear FE problems has several advantages over proprietary software. Some of the advantages include:

  1. Cost-effectiveness: Open-source software is usually free to use, which can significantly reduce costs for individuals and organizations.
  2. Customizability: Open source software can be customized to meet specific needs, allowing users to modify the software to suit their requirements.
  3. Transparency: Open source software is transparent, meaning that users can access and modify the source code. This makes it easier to understand how the software works and to identify and fix any issues.
  4. Community support: Open source software is often supported by a community of developers who contribute to its development and provide support to users.
  5. Interoperability: Open source software is often designed to be interoperable with other software, making it easier to integrate into existing workflows.

There are some limitations to using open source software for solving linear FE problems. One of the main limitations is the lack of support and documentation compared to commercial software. Additionally, open source software may not have all the features and capabilities that commercial software offers. However, open source software can often be customized and modified to meet specific needs, and it is generally more cost-effective than commercial software. Ultimately, the choice between open source and commercial software will depend on the specific needs and resources of the user.

What is FEA structural analysis?

FEA (Finite Element Analysis) structural analysis is a computerized method used to determine the behavior of structures under various conditions. It involves breaking down a complex system into smaller, more manageable elements and analyzing each one individually to determine how they interact with each other.

FEA can be used to optimize designs, reduce material costs, and improve performance and safety. It is commonly used in industries such as aerospace, automotive, and civil engineering.

FEA can be used to analyze mechanical components such as beams, plates, shells, and solid bodies. It can help determine stresses, displacements, and deformations in these structures under various loading conditions.

FEA is employed in the automotive industry to analyze vehicle components, including chassis, suspension systems, and engine components. It aids in optimizing the design for strength, durability, and performance.

FEA finds applications in the analysis of biomedical structures like prosthetics, implants, and medical devices. It helps evaluate the mechanical behavior and performance of these structures in biological environments.
