Hi, I am trying to do a hypersonic simulation with SU2NEMO, but i get this error:


Mutation++ has not been configured/compiled (add '-Denable-mpp=true' to your meson string) or 2) CODI must be deactivated since it is not compatible with Mutation++.


I downloaded Mutation++ from Github and I put it in the su2 folder, but i don't know if I have to do any further procedures.


Thank you in advance


PS I tried to put -Denable-mpp=true manually on the meson.py but it doesn't seem to solve the problem

you need the option -Denable-mpp=yes in the meson configuration

you also need to set this variable:

export MPP_DATA_DIRECTORY=$SU2_HOME/subprojects/Mutationpp/data

and the compiler needs to know where the mutation shared libraries are, so add the folder containing mutation to LD_LIBRARY_PATH

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

Thank you. When you say I need the option -Denable-mpp=yes in which file do I need to put that?
meson.build or meson.py or meson_options.txt ?

[bigfootedrockmidget]

It is an option that you add after the meson command on the command line, so

 ./meson.py build -Denable-mpp
