VELOCITY_ARROWS is a MATLAB program which makes an arrow plot of a velocity field, using XY and UV data stored as TABLE files.
The program is mainly a preprocessor for MATLAB's quiver routine. It reads the (X,Y) coordinates of a set of points from an "XY" file, and the corresponding horizontal and vertical velocities from a "UV" file. It then makes a few settings, calls quiver to plot the arrows, and also traces out the convex hull of the points, which is presumably the boundary of the region.

DIRECTION_ARROWS is a MATLAB program which plots the velocity direction field.
FREE_FEM_NAVIER_STOKES is a MATLAB program which solves the steady incompressible Navier Stokes equations on an arbitrary triangulated region, using the finite element method.
FREE_FEM_STOKES is a MATLAB program which computes the pressure and velocity for a Stokes flow. The velocity vectors can be plotted using VELOCITY_ARROWS.
TABLE is a data format which is used for the input files to this program.
VECTOR_MAGNITUDE_GRID is a MATLAB program which reads node and velocity data from a file, and using an interpolating function, is able to display a contour plot of the vector magnitude field.
VECTOR_STREAM_GRID is a MATLAB program which reads node and vector data from a file, computes an interpolatory function, evaluates on a uniform grid of points specified by the user, and displays a streamline plot of the vector field.
VECTOR_PLOT is a FORTRAN90 program which can read an XY file and a UV file and plot the velocity and velocity direction fields.
VELOCITY_ARROWS_GRID is a MATLAB program which reads files of node and velocity data, and, using interpolation, creates a vector plot with arrows place on a uniform grid of the user's specification.
VELOCITY_ARROWS_GRID2 is a MATLAB program which reads a single file of node and velocity data, and using interpolation is able to display a velocity vector field along any uniform grid of points specified by the user.
VELOCITY_ARROWS_SEQUENCE is a MATLAB program which can process a set of many data files with names that are numbered in sequence.
VELOCITY_ARROWS_SEQUENCE2, is a MATLAB program which reads a single XYUV file of nodes and velocities, plots the data and writes it to a PNG file, and then repeats the process for the next file.
VELOCITY_ARROWS2 is a MATLAB program which assumes that the XY and UV data are stored in a single table file.
CHANNEL is a problem involving flow in a horizontal channel.
