We combine our knowledge of academic and industrial engineering sectors with our state-of-the-art modelling expertise to deliver solutions for our clients. Our experience spans natural hazards, offshore engineering, foundation systems, and mining engineering. We are proficient in coupling numerical modelling with laboratory and site-specific testing to deliver results ranging from mid-size engineering applications to major government infrastructure projects.

CES-Lab uses a variety of in-house numerical codes and software packages. Our computational facilities include dedicated CES-Lab servers, University of Tasmania School of Engineering computational servers and the Tasmanian Partnership for Advanced Computing (TPAC) state-of-the-art High Performance Computing Cluster.

our expertise

complex multiphysics applications

Large Deformation

Simulation of large deformation behaviour requires advanced meshing techniques.

CES-Lab uses large deformation methods including Coupled Eulerian Lagrangian (CEL) Smoothed Particle Hydrodynamics (SPH) and Lattice Boltzman Method (LBM).

Fluid-Structure Interaction

Fluid-Structure Interaction (FSI) is a multiphysics coupling technique used to describe physical processes incorporating both structural mechanics and computational fluid dynamics. CES-Lab models FSI applications using the Coupled Eulerian Lagrangian method (CEL), the Arbitrary Lagrangian Eulerian method (ALE) and the Lattice Boltzman Method (LBM).

Advanced Constitutive Behaviour (Geotechnical)

Material constitutive behaviour is vital to the development of accurate models that can be calibrated against observed phenomena. Selection of an inappropriate constitutive model can result in simulations that do not provide representative behaviour. CES-Lab develops and implements a wide range of advanced constitutive models for computational geotechnics.

Fracture

Fracture Processes are important modelling the initiation and propagation of cracks and joints. Simulation of fracture requires numerical techniques capable of modelling crack growth. CES-Lab uses the eXtended Finite Element Method (xFEM) and the Element Deletion (ED) to model fracture processes.

Spatial Variation

Soils properties often vary from location to location. Incorporating of spatially variable properties can have profound consequences on simulation behaviour and are often necessary to capture real-life behaviour. CES-Lab uses probabilistic methods such as random field theory coupled with finite element methods to model uncertainty, risk and large variation.

Thermal

Simulation of heat transfer and thermal behaviour is essential for civil infrastructure, geotechnics and ocean engineering systems. CES-Lab models thermal problems involving convection, conduction and thermal radiation using advanced Computational Fluid Dynamics methods including Lattice Boltzman Method (LBM) and the Coupled Eulerian Lagrangian method.
