Pāhoehoe and ʻaʻā: material parameters for materials.lava and drawing options for MPMLava. Pāhoehoe is hotter,
runnier and gassier, with a thin ductile glassy crust that stretches and folds into ropes; ʻaʻā is cooler, more viscous
and crystal-rich, and its thicker brittle crust tears into dark clinker.
