Résumé

Vertex Block Descent (VBD) is a fast and robust method for the real-time simulation of deformable objects using the finite element method. Originally, the method is designed for the popular linear tetrahedral elements. However, these elements have low accuracy and introduce locking artifacts. In this context, we propose an extension of VBD in order to: (i) support any isoparametric elements and shape function orders; (ii) improve its performance even for high-order elements; and (iii) enhance convergence through the use of sub-stepping. Overall, using other types of elements enables more accurate results while maintaining a computational cost comparable to linear tetrahedra.
