To address this, we present Namako 2, an extended version of our previous Unity plugin that enables real-time finite element simulation with automatic mesh generation, 3D model embedding, robust contact handling, and built-in stress visualization. We demonstrate several example scenes of surgical simulation using Namako 2.
