=The Big Picture=
Need to compile the code in order to run the solver. Once compiled for either a serial or multi-core system, you can run the CFD solver. The solver requires two inputs: a mesh grid and a configuration file.
*Will add a few templates once we figure out realistic configuration cases for our rockets.
*Will add a sample mesh once we have one.
=Installation on personal computer=
General Tips:
*Learn how to navigate around your computer using just your terminal
*Understand how to edit .bashrc files
*Understand how to change path variables in your terminal
*If not compiling with cygwin due to some carriage return error, add this to your .bash_profile script (in your home directory)
<code>export SHELLOPTS</code>
<code>set -o igncr</code>
==Windows==
Install cygwin with g++, gcc, make, and cpp packages. You need to be able to compile C++ code. Need to figure which exact packages.
==Mac and Linux==
You already have a compiler, so download source code zip, unzip, and follow the tutorial on SU2’s site.

And obviously, change the paths to be correct. In order to find your .bashrc and open it in terminal:

Or you can open it in the GUI, by going to your home directory and pressing ctrl+h in order to show hidden files. Then double click your .bashrc file and add the specified lines.

At this point, you will be able to run the code from any directory. However, if the files aren't executing, you can change their permissions to make them executables. Go to the directory where you’ve compiled SU2 and run the following command on each module, like this:<code> corn17:~/SU2compiled/bin> chmod +x SU2_CFD</code>
=Running sample code=
The tutorial is really great. Read it. But also make sure to grab the sample mesh files from the separate test case repository: [https://github.com/su2code/TestCases Link to SU2 Testcase meshes]
You will need it to run the config files that come pre-prepped for you.
