An Object-Oriented Design for Two-Dimensional Vortex Particle Methods
TLDR
An object-oriented design used to implement a vortex particle based flow solver in two dimensions is described and the various abstractions that arose as a result of this design are provided.Abstract:
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 various abstractions that arose as a result of this design. Several of the algorithms have common components that may be abstracted and reused. We demonstrate how the design allowed us to derive the traditional benefits of OOD. In addition, we show how the design directly suggested elegant generalizations of existing algorithms. Finally, we show the benefits of using software testing techniques and building a powerful scripting layer for the library.read more

A method of local corrections for computing the velocity field due to a distribution of vortex blobs
TL;DR: A computationally efficient method for computing the velocity field due to a distribution of vortex blobs is presented in this article, which requires fewer calculations than the straightforward vortex method velocity procedure and does not sacrifice the higher-order accuracy.
