INOUT_FLOW_DISPLAY
Display an INOUT Flow Solution

INOUT_FLOW_DISPLAY is a MATLAB script that can display a snapshot of the velocity field from a dataset of solutions of a time-dependent incompressible parameterized flow problem in a cell with inflow and outflow.

The "INOUT" region is contained in the unit square, [0,1] x [0,1]. There is an inlet on the left side, from [0,0] to [0,0.2], and an outlet on the right side, from [1,0.8] to [1.0,1.0].
