2D thrombus formation model

Thrombus formation in pulsatile flow. Based on custom LBM solver.


Custom 2D LBM solver capable of handling porous materials and turbulence. OpenMP parallel design. Real-time monitoring tools. HDF5 data format. The simulation geometry can be "painted" in an image editor.

Theory guide Manual Download


GPU based fast solver. It can solve patient-specific blood flows in a few minutes on a regular desktop workstation.

Virtual stenting

Fast virtual insetion of flow diverters. The mechanical model of the different virtual stents are validated. The resulting surface used as a porous layer in CFD simulations.

Chaotic flows in diseased vessels

Quantifying chaotic properties inside brain arteries using residence-time.

Slurry mixer design

CFD study of large slury mixers to optimise mixing efficiency.

PIV methods

Optical tracking of small particles in a suspension using OpenCV library.

3D game engine (OpenGL)

Experimental game engine using octree space partitioning, keyframe animations, and basic physics.

Simplicial Quantum Gravity

One QG candidate based on monte-carlo random walk of possible simplicial structures making up space-time.

Highly accurate tracers

Accurate integration of tracer trajectories in transient flow fields inside pathologic vessels. The trajectories are used for chaotic flow quantifiations.
