Full Domain Analysis in Fluid Dynamics
Alexander Hagg, Adam Gaier, Dominik Wilde +3
Novel techniques in evolutionary optimization, simulation and machine learning allow for a broad analysis of domains like fluid dynamics, in which computation is expensive and flow…
Supersonic Shear and Wall-Bounded Flows With Body-Fitted Meshes Using the Semi-Lagrangian Lattice Boltzmann Method: Boundary Schemes and Applications
Philipp Spelten, Dominik Wilde, Mario Christopher Bedrunka +2
Lattice Boltzmann method (LBM) simulations of incompressible flows are nowadays common and well-established. However, for compressible turbulent flows with strong variable density…
Efficient Quality Diversity Optimization of 3D Buildings through 2D Pre-optimization
Alexander Hagg, Martin L. Kliemank, Alexander Asteroth +4
Quality diversity algorithms can be used to efficiently create a diverse set of solutions to inform engineers' intuition. But quality diversity is not efficient in very expensive p…
Lettuce: PyTorch-based Lattice Boltzmann Framework
Mario Christopher Bedrunka, Dominik Wilde, Martin Kliemank +3
The lattice Boltzmann method (LBM) is an efficient simulation technique for computational fluid mechanics and beyond. It is based on a simple stream-and-collide algorithm on Cartes…
Designing Air Flow with Surrogate-assisted Phenotypic Niching
Alexander Hagg, Dominik Wilde, Alexander Asteroth +1
In complex, expensive optimization domains we often narrowly focus on finding high performing solutions, instead of expanding our understanding of the domain itself. But what if we…
Cubature rules for weakly and fully compressible off-lattice Boltzmann methods
Dominik Wilde, Andreas Krämer, Mario Bedrunka +2
Off-lattice Boltzmann methods increase the flexibility and applicability of lattice Boltzmann methods by decoupling the discretizations of time, space, and particle velocities. How…
High-order semi-Lagrangian kinetic scheme for compressible turbulence
Dominik Wilde, Andreas Krämer, Dirk Reith +1
Turbulent compressible flows are traditionally simulated using explicit time integrators applied to discretized versions of the Navier-Stokes equations. However, the associated Cou…
Semi-Lagrangian lattice Boltzmann method for compressible flows
Dominik Wilde, Andreas Krämer, Dirk Reith +1
This work thoroughly investigates a semi-Lagrangian lattice Boltzmann (SLLBM) solver for compressible flows. In contrast to other LBM for compressible flows, the vertices are organ…
