24.10.2016Porting a Lattice-Boltzmann Flow Solver to GPU

The in-house software ZFS is a modular framework for the simulation of complex flows. One of the modules uses a Lattice-Boltzmann Method (LBM) to solve for the governing equations of flows. The LBM-code is massively parallelized and uses the Message Passing Interface (MPI) for inter-process communication and OpenMP for shared memory parallelization. The trend in High Performance Computing (HPC), however induces to use another level of parallelization by porting code to accelerators like NVIDIA GPUs or Intel Xeon Phis / Knights Landing. It is the aim of this thesis to port the existing LBM module of ZFS to an NVIDIA GPU and to investigate the performance gain obtainable by such an approach. The student will not only prepare a GPU implementation of the computational kernel but will also investigate the effort to transfer data to and from the GPU and the capability to hide the communication with other MPI processes and with the GPU behind the computation that is ideally balanced between both CPU and GPU.

07.11.2016Coupling Structure and Flow Solvers for the Simulation of Fluid-Structure Interaction

Nowadays, it becomes more and more important to accurately solve multi-physics problems by means of numerical simulations. This often requires to tightly couple different kinds of solvers that are responsible for the simulation of the different physics. This thesis should cover the direct coupling of a Lattice-Boltzmann flow solver and a structure solver to handle for Fluid-Structure Interaction (FSI) problems. Therefore, the student shall either integrate an existing structure solver into the in-house flow solver ZFS or use coupling libraries such as OpenPalm for the direct communication between an existing structure solver and ZFS. It is the aim to to have a working and efficient implementation at hand to simulate FSI problems in the field of bio-fluid mechanics on large scale supercomputers.

09.11.2016Workflow Automatization of a Nasal Cavity Flow Simulation Pipeline

The pipeline of simulating the respiratory flow in the human nasal cavity consists of multiple steps, i.e., the extraction of a smooth and realistic geometry of the airway from computer tomography images, generation of a computational mesh, the simulation itself, and the post-processing of the simulation data. These steps commonly obey a dependency chain and are in general performed step-by-step. An automatization of this workflow by stringing together established best-practice methods and algorithms would be beneficial for the simulation end user as well as of importance for the integration in clinical applications in the long run. The student should evaluate the available tools and should automate the individual steps of the workflow as well as the data exchange between the consecutive steps to end up with a black box for the simulation of nasal cavity flows.

09.11.2016Coupling a Level-Set Solver with a Lattice-Boltzmann Solver to Track Moving Boundaries

Simulating moving geometries in a rapidly changing flow is a challenging tasks. A lot of technical, biomedical, and generic multi-physics applications necessitate to consider moving geometries to realistically simulate the corresponding physical processes. Different methods are commonly applied to track moving surfaces in a flow, e.g., the geometry is physically moved, the mesh is deformed by Arbitrary Lagrangian (ALE) approaches, or a pure Lagrangian ansatz is followed. Representing the geometry as a level-set, however, comes at a lower cost and allows to use the corresponding signed-distance function as a distance measure to the surface that can easily be used to refine the computational mesh around the moving object. Such a level-set approach is already implemented in the in-house flow solver ZFS for a finite volume method. The aim of this thesis is to couple the available level-set solver to the Lattice-Boltzmann flow solver in ZFS as well to enable easy surface tracking and dynamic refinement of the computational mesh.

22.11.2016Implementation of a Particle Evaporization Model for the Numerical Analysis of Allicin Deposition in the Human Airways

Allicin is a cytotoxical product that might be capable of treating lung diseases like infections by streptococci. However, it is not well understood how such a treatment should ideally look like, i.e., what the optimal dose of allicin is, how the temperature influences its evaporization, and where the drug deposits in the human lung to take effect. Therefore, numerical simulations using a Euler-Lagrangian approach for the two-phase flow that accompany an experiment performed at the Institute of Aerodynamics are planned. To perform such simulations the available Lattice-Boltzmann flow solver and the Lagrangian particle solver need to be extended to account for particle evaporization. As such, a model for the evaporization including particle shrinkage as well as source-term definitions for a passive scalar are to be implemented by the student. The results of subsequent simulations should be juxtaposed to the corresponding experimental findings and a statistical analysis of the deposition and evaporization behavior should be performed.
