The subject of simulating internal organs is a valuable and important topic of research to multiple fields from medical analysis to education and training. This paper presents a solution that utilizes a graphical technique in combination with a Stochastic method for tuning an active physics-based model. We generate responsive interactive organ animations with regional properties (i.e., areas of the model oscillating with different harmonic frequencies) to reproduce and capture real-world characteristics. Our method builds upon biological and physical discoveries to procedurally generate internally controlled rhythmic motions but also enable the solution to be interactive and adaptive. We briefly review deformation models for medical simulations and investigate the impediments to combining 'computergraphics' representations with biomechanical models. Finally, we present a lightweight solution that is scalable and able to procedurally generate large organ animations. In particular, simplified geometric representations of deformable structures that use periodic coupled forces to drive themselves.
