Mayavi is an open-source, general-purpose, 3D scientific visualization package. It seeks to provide easy and interactive tools for data visualization that fit with the scientific user's workflow. For this purpose, Mayavi provides several entry points: a full-blown interactive application; a Python library with both a MATLAB-like interface focused on easy(More)
Visualizing CFD data is extremely important. There are very few freely available tools that allow one to visualize scalar and vector data on rectilinear, structured and unstructured grids. MayaVi is a free tool developed by the author that helps visualize such CFD data. It uses the Visualization Toolkit (VTK) for the actual visualization and provides a(More)
Higher order panel methods are used to solve the Laplace equation in the presence of complex geometries. These methods are useful when globally accurate velocity or potential fields are desired as in the case of vortex based fluid flow solvers. This paper develops a fast multipole algorithm to compute velocity fields due to higher order, two-dimensional(More)
Vortex methods offer a grid-free alternative to simulating incompressible, viscous, fluid flows. They require the use of fairly sophisticated algorithms and can be complicated to implement for general flows. This article describes an object-oriented design used to implement a vortex particle based flow solver in two dimensions. We provide an overview of the(More)
—We evaluate the performance of different load balancing algorithms when used with the Smooth Particle Hydro-dynamics (SPH) particle method. We compare several geometric algorithms and a serial graph partitioning algorithm (Metis) in terms of the efficiency and quality of partitioning. We find that the geometric partitioners are better suited with the RIB(More)
