A WebGL accelerated finite element mesh viewer.
To launch the application, go to the following URL:
https://mikolalysenko.github.io/femgl/index.html
Custom meshes may be inspected by dragging a file onto the page.
To translate existing data into the web format a conversion script is provided which is written in python (see convert/convert.py). Some example data is contained in the data/ folder of this repository and a demonstration of how to convert this can be found in convert/example.py.
Each mesh is a JSON object consisting of coordinate data, displacements, elements and palette information. The mesh JSON object must have the following properties:
An array of length 3 arrays storing the coordinates of each node in the mesh.
An array of length 3 arrays giving the displacement of each node in the mesh.
An array of groups of elements. Each element group is a JSON object with the following properties:
The type of the element. Currently only the following element types are supported:
P6A parabolic triangular elementP8A parabolic quadrilateral element
An array of per-element stress values
An array of arrays giving the vertex indices for each cell in the mesh.
An array of length 3 arrays giving the palette texture in RGB color space.
First, you will need to clone this repo and then install all of its dependencies:
git clone git@github.com:mikolalysenko/femgl.git
cd femgl
npm install
After this is done you can then run the program locally using budo via the following command:
npm start
Or build a standalone page with the command:
npm run build-page
