A JavaScript Finite Element Simulation Library

FEAScript is a lightweight finite element simulation library developed in JavaScript. It allows users to create and run client-side, browser-based simulations for physics and engineering problems without requiring additional installations. FEAScript serves as an excellent tool for building interactive web applications and facilitates hands-on learning of computational mechanics by providing a versatile platform to explore and solve complex problems. Our goal is to democratize finite element analysis by making simulation capabilities accessible to everyone, everywhere.

Getting Started

FEAScript requires only a simple HTML page to operate. All simulations are executed locally in your browser, without the need for any cloud services. The entire workflow is performed using JavaScript objects directly in the HTML file.

There are two ways to create simulations with FEAScript:

JavaScript API: For developers comfortable with coding, the JavaScript API provides full programmatic control, allowing direct integration into websites or web applications.
Visual Editor: The FEAScript platform provides a no-code, block-based interface for creating simulations without writing any JavaScript code.

🚧 FEAScript is currently under heavy development with new features being added regularly. Interested in contributing? Please check out our contribution guidelines to get started.

Features

The following lists contain some, but not all, of the available features in FEAScript:

Physical Modelling
- Solid heat conduction solver
Numerical Solution
- General form differential equations solver (under development)
- Linear system solvers (LU decomposition, Jacobi method)
Parallelization
- Web worker support for multi-threaded computation
Geometry and Meshing
- Simple mesh generation (1D and rectangular 2D domains)
- Unstructured mesh import from Gmsh (.msh file format)
Visualization
- Line and surface plotting

For a visual approach to creating simulations, we are also developing the FEAScript platform - a browser-based visual editor built on the Blockly External Link Icon library. This no-code interface allows users to build and run finite element simulations directly in their browser by connecting visual blocks. While FEAScript's JavaScript API offers full programmatic control for advanced customization, the FEAScript platform provides an accessible entry point for users without coding experience. FEAScript platform also provides the ability to save and load projects in XML format, enabling easy sharing and reuse of simulation configurations.

Tutorials

Below, you can explore tutorials that provide a step-by-step introduction to FEAScript. These tutorials show you how to use FEAScript's JavaScript API directly - for integrating finite element simulations into your own websites and applications - or how to use the FEAScript platform visual editor for a no-code experience.
