TOOL: GH-PlugIn to Visualize Vectorfields

v1.0.1.0 release for grasshopper 0.8.0013

flowL is a plug-in to visualize a vector field, generated trough positive and negative point charges.
The path lines are calculated with the “Runge-Kutta 4th Order Method” short “RK4”, developed by the German mathematicians C. Runge and M.W. Kutta. around 1900.

you can find it in the download section

 - vectorfield: generated with 2 positive (magenta) and 1 negative (cyan) charges - streamlines/pathlines: paths following the directions of the vectorfield - equipotential lines marks the areas with the same potential
