Andreas<p>Hello, world! Wait, for a nonlinear simulation <a href="https://mathstodon.xyz/tags/python" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>python</span></a> package? If you'd like to use FElupe for your <a href="https://mathstodon.xyz/tags/hyperelastic" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>hyperelastic</span></a> <a href="https://mathstodon.xyz/tags/simulation" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>simulation</span></a> but don't know where to start &amp; too lazy to read the docs, you may use the hello_world() function to print a minimal-working example to the console.</p><p>Initially, I wasn't sure if that kind of function really makes sense. But it turns out that I'm using this one quite frequently. 📝 (shhh!

Andreas<p>Here's an example: let's take the Neo-Hookean [1] isotropic <a href="https://mathstodon.xyz/tags/hyperelastic" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>hyperelastic</span></a> material model formulation. Just define its strain energy density function and use it in your <a href="https://mathstodon.xyz/tags/simulation" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>simulation</span></a> [2]. </p><p>[1] <a href="https://en.wikipedia.org/wiki/Neo-Hookean_solid" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">en.wikipedia.org/wiki/Neo-Hook</span><span class="invisible">ean_solid</span></a></p><p>[2] <a href="https://github.com/adtzlr/felupe" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="">github.com/adtzlr/felupe</span><span class="invisible"></span></a></p><p><a href="https://mathstodon.xyz/tags/python" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>python</span></a> <a href="https://mathstodon.xyz/tags/scientificcomputing" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>scientificcomputing</span></a> <a href="https://mathstodon.xyz/tags/finiteelementmethod" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>finiteelementmethod</span></a> <a href="https://mathstodon.xyz/tags/computationalmechanics" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>computationalmechanics</span></a> <a href="https://mathstodon.xyz/tags/fea" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>fea</span></a> <a href="https://mathstodon.xyz/tags/fem" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>fem</span></a> <a href="https://mathstodon.xyz/tags/jax" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>jax</span></a></p>
