On the Compatibility of DEIM Subspaces for Nonlinear Forces Reduction in Projective Dynamics
Shaimaa Monem Abdelhafez, Igor Pontes Duff, Peter Benner
In physics-based simulations, the evaluation of nonlinear constraint forces represents a primary source of computational complexity. Within the framework of projective dynamics, th…

An approach to encode divergence-free stress fields in neural approximations based on stress potentials
Mohammad S. Khorrami, Pawan Goyal, Soroush Motahari +5
The purpose of the current work is the development of an approach to account for quasi-static mechanical equilibrium in empirical (i.e., data-based) models for the stress field emp…
