Hi,
Have the NEMO and Mutation ++ been merged with the latest version of release 8.1 ?. I am from the IBM 360/44 , DEC1090, IBM 3090 era hence I am clueless about building an executable from scratch. I have used previous versions of SU2 binaries (albeit standard air models) and want to venture into high speed flows. Any help is greatly appreciated.

Thanks in Advance

NEMO is part of SU2. Mutation++ is a separate external library, and you will need to recompile SU2 to use it.



If you are currently running a linux system, then compiling is easy, just check out the docs here:
https://su2code.github.io/docs_v7/Bu...2-Linux-MacOS/
If you do not have linux, I recommend installing it or running a linux virtual machine to have access to all the programming and compilation tools.

Thanks a lot for the quick reply and I will try it out. However, I have Ubuntu installed through WSL 2, and i am able to run Linux commands on that. Would the process described on the web page still work or do I need to set up a duel boot system?
Thanks in advance

Sure, just try the following steps below to download su2
by making a clone from the github repository, then go to the directory and
create the configuration files and compile the code. The compiled binaries will be in the subdirectory
given by --prefix.

git clone https://github.com/su2code/SU2.git
cd SU2
./meson.py build --prefix=~/SU2/bin
./ninja -C build install

Thank you for the reply. Unfortunately, I get the "libmutation__.so" missing error. I saw another one of your posts and exported the paths you suggested but with no success. I wonder if the fact that I have been using SU2_7.x executables in my Windows side messing up this build ?. Would uninstalling those windows executables help in this case?
Thanks in advance

Actions I took in order to build and install SU2 &Mutation++
1. I deleted all previous versions of SU2 from my Windows side directory
2. Wiped all previous SU2 clones from Ubuntu and did the following
3. git clone https://github.com/su2code/SU2.git
4. sudo ./meson.py build -Denable-mpp=True -Denable-coolprop=True --prefix=~/SU2/bin
5. sudo ./ninja -C build install
6. export MPP_DATA_DIRECTORY=$SU2_HOME/subprojects/Mutationpp/data
Mutationpp[/B][/COLOR]
7. export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$SU2/subprojects/Mutationpp

I still get the same error (screenshot attached), any help is highly appreciated
SU2_CFD: error while loading shared libraries: libmutation__.so: cannot open shared object file: No such file or directory

[bigfootedrockmidget]

Do you have mutation++ installed in the folder

su2/subprojects/Mutationpp
and did mutationpp create a file libmutation__.so somewhere? In my case it is in su2/lib

[hk.narahari]

Yes libmutation__.so is created in the following directory
/SU2/build/subprojects/Mutationpp
Where should it be moved ?

[bigfootedrockmidget]

LD_LIBRARY_PATH is used to find the libraries, you need to change it to:

 export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$SU2_HOME/build/subprojects/Mutationpp

edit: you have to check if $SU2_HOME is correct as well, such that the entire path is correct:
echo $SU2_HOME

Hi,
I got swamped with other work and overlooked this post. Thank you for the help in resolving the issue.
