Abstract
The increasing complexity of dynamic simulations involving unilateral constraints, such as contacts, is pushing for new solvers that may address the problem of handling non-smooth impact events in a more efficient and accurate manner, especially in mixed rigid and flexible-bodies simulations. For this purpose, a new implementation of an interior-point solver for Quadratic Cone Programming is proposed. Even though the general idea of considering multibody system formulations as a parallel of an optimization/programming problem is already known in literature ([3, 4, 6]), still very few options are available for those problems whose complexity is due to contacts with friction and finite-elements at the same time. The opportunity to handle those problems in a unified numerical framework could trigger a novel interest both in scientific and applied researches.

The solver has been tested with many more element types, provided by the Chrono library: linear, quadratic, non-linear, isogeometric formulations with and without plasticity, geometric and material non-linearity, beams, shells, solids, cables,...
