  • Jul 2017
We present several simulations carried out using Chrono::FSI and Chrono::Vehicle that highlight the two way coupling between the dynamics of a vehicle and the dynamics of a fluid that is free to move in a tank rigidly attached to the vehicle; i.e., a vehicle sloshing problem. The simulations are carried out in Chrono [1] using a monolithic solution...

We present a Smoothed Particle Hydrodynamic model for incompressible fluids. As opposed to solving a pressure Poisson equation, which is very costly, here incompressibility is achieved by requiring as a kinematic constrain that the volume of the fluid particles is constant. We use Lagrangian multipliers to enforce this restriction. These Lagrange m...

... In addition to providing Chrono users with the expected benefits of template-based ground vehicle modelling, Chrono::Vehicle was also architected and designed to leverage existing and future extensions modelling capabilities in Chrono and capitalise on its underlying high-performance and parallel computing facilities. Chrono::Vehicle models can be easily incorporated in complex, multiphysics simulations, such as flexible tyres on granular terrain , FSI fording scenarios (Mazhar et al., 2017), and autonomous and connected vehicle tests (Elmquist et al., 2017). ...
... In conjunction with the Chrono::FSI module, Chrono::Vehicle has been used in FSI problems to simulate fording manoeuvres and sloshing of liquids in vehicle-mounted tanks (Mazhar et al., 2017). These simulations capture the two-way coupling between the vehicle dynamics and the fluid phase, the latter being governed by the mass and momentum (Navier-Stokes) equations discretised in space via SPH. ...
