Installation

FEAScript 0.2.0 solves linear systems with math.js, which it expects as a global math object. Load math.js before you call solve(), as shown below.

In the browser

Load math.js with a <script> tag, then import the ES module build of FEAScript 0.2.0 from a CDN:

<script src="https://cdnjs.cloudflare.com/ajax/libs/mathjs/11.12.0/math.min.js"></script>

<script type="module">
  import { FEAScriptModel } from "https://cdn.jsdelivr.net/npm/feascript@0.2.0/dist/feascript.esm.js";
</script>

note

https://core.feascript.com/dist/feascript.esm.js always serves the latest release of FEAScript, not 0.2.0. Pin the version in the URL, as above, to keep using 0.2.0.

FEAScriptWorker and the "jacobi-gpu" solver start web workers whose scripts are not part of the bundled build. To use them, import the source modules instead:

import { FEAScriptWorker } from "https://cdn.jsdelivr.net/npm/feascript@0.2.0/src/index.js";

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

With Node.js

npm install feascript@0.2.0 mathjs

import * as math from "mathjs";
global.math = math;

import { FEAScriptModel } from "feascript";

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

Optional dependencies

The plotting functions use Plotly, through the global Plotly object. In the browser, load plotly.min.js with a <script> tag (see Visualization).
