Display an INOUT Flow Solution

**INOUT_FLOW_DISPLAY**
is a MATLAB program which
displays 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].

+-----------------------+ |+----------------------+ || ---> || OUT-----> || ---> || ++ || || || || || || || || ++ || ---> || IN-----> || ---> || +----------------------+| +-----------------------+There are 1,681 nodes in a 41 by 41 evenly spaced grid. The nodes are organized into 800 6-node triangular elements which are quadratic in velocity and linear in pressure.

- inout_flow_display.m, is a MATLAB M function file which can plot the region, the elements, the velocity direction field, or velocity direction vectors.

Input data files:

- inout_flow_xy.txt, the XY coordinates associated with the nodes.
- inout_flow_elements.txt, the node indices that make up each element.
- inout_flow_step001.txt, the data for the solution at time step 1.
- inout_flow_step100.txt, the data for the solution at time step 100.
- inout_flow_steady.txt, the data for the steady state solution.

Output graphic files:

- inout_flow_region.png, a PNG image of the region.
- inout_flow_elements.png, a PNG image of the elements.
- inout_flow_step001_dir.png, a PNG image of the normalized velocity or direction field at time step 1.
- inout_flow_step001_vec.png, a PNG image of the unnormalized velocity field at time step 1.
- inout_flow_step100_dir.png, a PNG image of the normalized velocity or direction field at time step 100.
- inout_flow_step100_vec.png, a PNG image of the unnormalized velocity field at time step 100.
- inout_flow_steady_dir.png, a PNG image of the normalized velocity or direction field for the steady state.
