Computational Fluid Dynamics with Embedded Cut Cells on Graphics Hardware
… of fluid dynamics simulations featuring embedded cut cells using the CUDA programming platform. We demonstrate efficient generation and handling of geometric surface data in rectilinear computational grids. This is added to a split Euler solver to define piecewise linear cut cells describing solid …

Anisotropic output-based adaptation with tetrahedral cut cells for compressible flows
… a finite-volume discretization for tetrahedral cut-cells is developed that makes possible robust, anisotropic adaptation on complex bodies. Through grid refinement studies on inviscid flows, this cut-cell discretization is shown to produce similar accuracy as boundary-conforming meshes with a …

A simplex cut-cell adaptive method for high-order discretizations of the compressible Navier-Stokes equations
… for high-order discretizations and simplex, cut-cell mesh generation. First, output-based mesh adaptation consists of generating a sequence of meshes in an automated fashion with the goal of minimizing an estimate of the error in an engineering output. This technique is proposed as an …

On a Cartesian cut-cell methodology for simulating atmospheric ice accretion on aircraft
… icing process. We integrate it with a Cartesian cut-cell method which can cope dynamically with moving interfaces. The robustness and performance of the cut-cell techniques allow us to simulate ice growth on real-world geometries. We demonstrate this capability by presenting results of the …

Photovoltaic Module Reliability - a Study on Cell Mismatch
… Explicit solutions to the diode model for solar cells in the model allow for fast computation and easier implementation into other simulation models. Electroluminescence images of cells at reverse bias are used to characterize the distribution of reverse leakage current and verified to provide …

High performance simulations of yield stress fluids in a structured adaptive mesh refinement framework with embedded boundaries
Viscoplastic fluids are a class of non-Newtonian liquids characterised by their yield stress. Unless an external stress is applied which is larger than this threshold value, the fluid does not flow, but exhibits rigid body behaviour. Above the yield stress, applied forces cause viscous deformation. …
