High-Resolution Interaction with Corotational Coarsening Models

Rosell Torres, doctoranda del área simulación física, nos presentará uno de sus últimos trabajos. This work presents a numerical coarsening method for corotational elasticity, which enables interactive large deformation of high-resolution heterogeneous objects. The method derives a coarse elastic model from a high-resolution discretization of corotational elasticity with high-resolution boundary conditions. This is in contrast to previous coarsening methods, which derive a coarse elastic model from an unconstrained high-resolution discretization of regular linear elasticity, and then apply corotational computations directly on the coarse setting. Previous approaches fail to handle high-resolution boundary conditions correctly, suffering accuracy and robustness problems. The method, on the other hand, supports efficiently accurate high-resolution boundary conditions, which are fundamental for rich interaction with high-resolution heterogeneous models. They demonstrate the potential of our method for interactive deformation of complex medical imaging data sets.
