Mayavi is a general purpose, open source 3D scientific visualization package that is tightly integrated with the rich ecosystem of Python scientific packages. Mayavi provides a continuum of tools for developing scientific applications, ranging from interactive and script-based data visualization in Python to full-blown custom end-user applications.
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)
An electrostatic comb-drive has been proposed and designed for actuating a bistable buckled-beam mechanism. The possibility of operating this structure as a resonator has been explored and the mechanical resonance frequencies have been determined. The performance of this system has been predicted by means of simulations and test structure designs have been(More)
