Towards Long-Time Simulation of Soft Tissue Simulant Penetration

We present a conceptual discussion of a numerical method to simulate the penetration of a ballistic gel by a projectile. The method draws on the computational advantages presented by asynchronous variational integrators (AVIs) and an immersed boundary method to result in an easily parallelizable, efficient and adaptive algorithm. The paper focuses on the algorithmic ideas involved– at the expense of details and a simplified model.
