Purpose: The purpose of this project is to provide a powerful,
reliable, open source vortex method for scientists, engineers and mathematicians.
BlobFlow(TM) is a general Navier-Stokes solver for two-dimensional, incompressible
flows. It is a variation of the vortex method, and as such, will
be most effective when used for flows dominated by isolated regions of
vorticity. This particular variation is based on elliptical Gaussian
basis functions and the formal term for the algorithm is the "elliptical
corrected core spreading vortex method" or ECCSVM, for short. The
documentation covers the specifics in a little more detail.
