Abstract:

With the continued increase in power of the modern computer, more computational problems are tractable via computer simulation, leading to fast production of data, analysis, and quantitative solutions. Discrete three dimensional analyses, including those involving computational fluid dynamics, now show even more promise as the time required to meet solutions has been shown, in some instances, to be on the order of hours and days rather than weeks or months for the same problem. As a means to exploit such computational power, a MATLAB algorithm has been developed for use with computational meshes in applications requiring the rotation of a mesh about an axis. The algorithm, called ROTATESTL, has been developed such that any number of original mesh files in stereolithography file format can be rotated by any number of angular deflections about specified rotation axes. The algorithm is platform portable and runs on both Windows and Linux operating systems supporting MATLAB 7.
