Installation

In the browser

Import the ES module build from the hosted build or from a CDN:

<script type="module">
  import { FEAScriptModel } from "https://core.feascript.com/dist/feascript.esm.js";
</script>

<script type="module">
  import { FEAScriptModel } from "https://cdn.jsdelivr.net/gh/FEAScript/FEAScript-core/dist/feascript.esm.js";
</script>

You can also download a release from GitHub Releases and import it locally.

With Node.js

npm install feascript

import { FEAScriptModel } from "feascript";

FEAScript is built as an ES module. In a new project, set "type": "module" in your package.json.

Optional dependencies

FEAScript itself needs no extra setup to solve a model. The plotting functions use two optional libraries:

Library	Used by	Browser	npm
Plotly	plotSolution, plotInterpolatedSolution	Load plotly.min.js with a <script> tag (global Plotly)	npm install plotly.js
vtk.js	plotSolutionVtk, plotInterpolatedSolutionVtk, VTK export	Map @kitware/vtk.js/ with an import map	npm install @kitware/vtk.js

See Visualization for the details.
