For those willing to run fluid-only computations - i.e. to skip the structural and thermal analysis (using AEROS) for the medium fidelity level - we provide a specific installation procedure.

The differences with the 'full' installation are the following:

  • Only the Gmsh executable is required, not the Gmsh libraries and include files.
  • A different setup file is provided for meshutils (called setup_fluid_only.py in the ./multif directory).
  • It is not required to have AEROS installed.

Fluid-only installation steps

  • Install the custom version of SU2, such as explained in the Installation page.
  • Setup meshutils:
$ cd ./multif
$ rm -f *.so
$ python setup_fluid_only.py build_ext --inplace
  • Download the Gmsh executable from http://gmsh.info/src/) or build it from its source code. NB: Building the Gmsh libraries is not required.

Running the fluid-only version

Running the fluid-only version is similar to running the 'full' MULTIF version. Note that all the parameters related to the definition of the nozzle wall will be read but not taken into account in the analysis. Also, the module will output a "-1" value instead of any stress quantity the user might require to output.
