A multiscale model for real-time simulation of terrain dynamics is explored. To represent the
dynamics on different scales the model combines the description of soil as a continuous …

We investigate how well a physics-based simulator can replicate a real wheel loader
performing bucket filling in a pile of soil. The comparison is made using field-test time series …

This paper addresses the challenges of creating realistic models of soil for simulations of
heavy vehicles on weak terrain. We modelled dense soils using the discrete element …

A method for simulation-based development of robotic rock loading systems is described
and tested. The idea is to first formulate a generic loading strategy as a function of the shape …

In this paper, we propose a stabilized dimensional factorization (SDF) preconditioner for
saddle point problems arising from the discretization of Navier-Stokes equations. The idea is …

We consider real-time simulation of multibody systems in the context of a virtual environment
training simulator for sailors manipulating anchoring and tugging cables for stabilizing oil …

Optimizing the loading process of a front loader vehicle is a challenging task. The design
space is large and depends on the design of the vehicle, the strategy of the loading process …

A model of a tracked vehicle is described which reprents shoes, rollers, idler, sprocket and
chassis, refered to as the wheels henceforth, as rigid bodies. The connections between …

Simulations are an important part of today's society. Not only for performance optimization,
but also for training, education, research and games. It is a way to study systems that for …

We present an event driven adaptive time stepper for the simulation of the dynamics of
switching electronic circuits with an application to power inverters. We show that in this …
