Lagrangian tracer
TīmeklisEach lagrangian tracer will use the hydrodynamic field with the higher priority depending on the tracer position. By default the priority is define inverting the tree.dat order. The user can specify the oder using a block define in the lagrangian input file where the user can define the model priority: TīmeklisLagrangian Stretching and Polymeric Stress Fields for Weakly Viscoelastic Flows. In the limit of small Weissenberg number (Wi ≪ 1), we first derive an analytical relationship between the trace of the polymeric stress tensor and the Lagrangian stretching field for simple, linear flows.

The Lagrangian tracking module is implemented using the individual-based particle-tracking method which treats particles as if they exactly … TīmeklisIn the past five years, my research has involved theory, modelling, and simulation of traffic and transportation networks. I focussed on innovative approaches to collect microscopic traffic data and the use of these data to underpin the models and theories that I have developed, using new techniques for model identification. In the …
