We offer projects mainly in computational science and engineering. Your background could be applied mathematics, computer science, computational physics, control, mechanical engineering, robotics - but this is not exclusive. Please contact us with your interest and CV. Feel free also to propose thesis project by yourself.
Announced projects
Merge/split in rigid multibody simulation
Adaptive simplification of rigid multibody systems by merging bodies into agglomerate superbodies can accelerate large-scale simulation by many orders in magnitude. The actions must preserves physical invariants, minimizes computational time, produce consistent pressure force distributions and allow for impulse propagation. Application to vehicle or robot simulations with large piles of contacting bodies.
Comparative study between different rigid body simulation software
Study quantitative results in dynamics, computational performance, memory managment and parallelization opportunities between different rigid body simulation software. Both theory and numerical experiments with a set of test scenes relevant for using the software for virtual prototyping of complex mechanical systems. The softwares are (tentative list) AgX Multiphysics, Bullet Physics, EDEM.
Quantitative analysis of frictional contact models and solvers
Implement different formulations of dry friction for rigid bodies - some old and some new; performance analysis including: testing pipeline, design of statistical measures, scientific visualization of results.
Adaptive resolution in particle fluid simulation
Extension of existing constraint based particle fluids to adaptive level of detail. Alternatives to particle representation of coarse grained regions. Application to industrial systems or scientific studies of ocean freak waves.
Real-time simulation models of ground-tire interaction and transmission lines
New contact model for ground-tire interaction suitable for real-time simulation of constrained multibody systems. Constraint based modeling of transmission lines. Applications to new design of terrain vehicles.
New contact and friction models
Contact reduction (theory, implementation, analysis); evaluation of a number of existing contact models (implementation, analysis) of Anitescu/Potra, Anitescu/Hart, Kaufamn/Pai, pairwise models, Kane/Pandolfi; development of a new model including reduction, delocalization and aspirity (theory, implementation, analysis); splitting technique for friction LCP solver.
