This page will help you with installing SU2, as well as provide specific help with the way we use SU2.

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)

export SHELLOPTS

set -o igncr

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.

Installation in Corn

How to set up VNC for your computer

Don’t bother attempting to move files around with Filezilla. Login to a VNC session and execute the firefox command in the terminal. Go to SU2's github repository and download everything there. Navigate to the zip file and unzip the files. Navigate to the new path and execute these commands:

./configure --prefix="/afs/.ir/users/i/a/iangomez/SU2compiled/" CXXFLAGS="-03" --enable-mpi --with-cc=/usr/bin/mpicc --with-cxx=/usr/bin/mpicxx

make -j 8 install

Note: change the prefix to your directory! If you’re confused by this read ./configure --help or email Ian or your RCC.

Once it’s compiled, you need to add the export commands they give you to your .bashrc file:

export SU2_RUN="/afs/.ir/users/i/a/iangomez/SU2compiled/bin"\\ export SU2_HOME="/afs/.ir/users/i/a/iangomez/SU2-master"

export PATH=$PATH:$SU2_RUN

export PYTHONPATH=$PYTHONPATH:$SU2_RUN

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

cd

ls -al

vim .bashrc

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. Make sure to execute the bash file to get the PATH updated: exec bash.

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: corn17:~/SU2compiled/bin> chmod +x SU2_CFD

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: Link to SU2 Testcase meshes You will need it to run the config files that come pre-prepped for you.
