SPIRAL_DATA , a MATLAB library which computes a velocity vector field that satisfies the continuity equation, writing the data to a file that can be plotted by gnuplot. CFDTool™ is a MATLAB® Computational Fluid Dynamics (CFD) Toolbox for modeling and simulation of fluid flows with coupled heat transfer. I'm pretty new to different plots in Matlab and I'm trying to write a code that will show the flow field around a cylinder in Matlab. Flow Simulation using Solidworks.
