  • question about the assignment of lesson 19

    Posted by Xin on February 8, 2024 at 4:23 pm

    Hi Support team,

    I am doing assingment 19, and copy the tutorial folder RAS/sonicFoam but there are no mesh file and any blockMeshDict or snappyHexMesh file. I copy the resourses file of nacaairfoil and unzip it but there are files below. Can you please explain how i can generate mesh.

    Thank you in advance

    Hi Xin,

    First rule: if you dont know how to proceed and a tutorial always look at .Allrun file inside case to see each steps of process.

    As you can see here that mesh is converted from starccm to openfoam. So you dont need to use blockMesh or snappy here.

    !/bin/sh
    cd "${0%/*}" || exit                                # Run from this directory
    . ${WM_PROJECT_DIR:?}/bin/tools/RunFunctions        # Tutorial run functions
    #------------------------------------------------------------------------------
    
    restore0Dir
    
    # Convert mesh from resources directory
    runApplication star4ToFoam -scale 1 \
        "$FOAM_TUTORIALS"/resources/geometry/nacaAirfoil/nacaAirfoil
    
    # Symmetry plane -> empty
    sed -i -e 's/symmetry\([)]*;\)/empty\1/' constant/polyMesh/boundary
    
    # Don't need these extra files (from star4ToFoam conversion)
    rm -f \
       constant/cellTable \
       constant/polyMesh/cellTableId \
       constant/polyMesh/interfaces  \
       constant/polyMesh/origCellId  \
       ;
    
    if isParallel "$@"
    then
    
        runApplication decomposePar
    
        runParallel $(getApplication)
    
    else
    
        runApplication $(getApplication)
    
    fi
