Streamline Flow Visualization with Matlab

SFVM

SFVM is an integrated Matlab application complete with a Graphical User Interface (GUI) and a plotting window that generates streamline patterms for a broad range of flows. The application is ideal for self-study and as a teaching supplement in undergraduate and graduate classes of fluid mechanics, software design and matlab programming. SFVM was developed by Christine Valley and Yair Treister in the Spring of 2006 based on a Fortran prototype by C. Pozrikidis included in CFDLAB which is based on the fluid dynamics library FDLIB.
