Finite Element Analysis

You will study, run, and modify a supplied Finite Element Analysis $($FEA$)$ program.

Download and run $$FEAtext$.$cpp$$ and $$FEApixel$.$cpp$.$ Make some kind of changes to one or both of

them and turn in the modified code and output.

Also posted for your reference are $$BMPprocessor$.$cpp$$ and its input test file $$in$.$bmp$.$ You can use

these as a base to create a program that can read and write data to$-$from $24-$bit bmp files. You can

create these files with paint and other bitmap editors. Paint.NET is a very good free bmp editor, available

on the innerwebernets.

For example, you could do ONE OR ALL of the above:

$1)$ Change the transfer function by using some other rules of physics like Bernoulli$$s Principle or

the Gas Laws. Or$,$ just some unique rules you make up yourself.

$2)$ Add some more blockages, or a more complex $$maze$$ or $$venturi$$ to simulate fluid flow in a

more interesting way.

$3)$ Extend the program to read in data from a large file, perhaps read a prepared bitmap.bmp file

and use that to initialize a large map with blockages and initial Q sources. $($Red could be

blocked, Black could be Q$).$ You could also use grayscale values to represent height, and

use that to modify flow rates.

a$.$ Write the intermediate and$/$or results back to a bitmap file! That would be way cool!

b$.$ If you have an animated gif editor and know how to do that, compile a series of bmp$$s

into an animated gif.

$4)$ Extend the program into a $3-$Dimensional rectangular array.

$5)$ Extend the program to use tetrahedral polygons $($aka mesh, stl format, etc$)$ instead of cubes.

This may require a graph representation. Good luck with that!

$6)$ Some other change$($s$),$ be creative!

Everything outlined above, with proper formatting. Please also email me anything that is super cool.
