Because it's relatively less known than other numerical methods, possibly undeservingly so, and because I love it.</p><p>So what is it? SPH is a Lagrangian meshless numerical method primarily used for <a href="https://fediscience.org/tags/ComputationalFluidDynamics" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ComputationalFluidDynamics</span></a> (and more recently also <a href="https://fediscience.org/tags/ComputationalMechanics" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ComputationalMechanics</span></a>).</p>
