This package provides data processing and conversion between NetCDF and OpenFOAM data types. It uses a WMake based build system to align with the OpenFOAM build framework. It requires that the NetCDF library be installed to the lib/ directory. Additionally, a local copy of OpenFOAM should be installed with sufficient permissions for the user to be able to write a new executable to the ${FOAM_APPBIN} directory. Before building our executable, the user will need to source the OpenFOAM bashrc to set the relevant $FOAM_ environment variables. Only one additional configuration step is required for our utility, which is to export an environment variable ${ncdfToFoamRoot} to the top level directory of this repo as:

$ export ncdfToFoamRoot=/path/to/git/clone

The ncdfToFoam utility can be compiled from the top level directory of this repo by executing:

$ wmake src

The compilation can be verified by entering the test directory and executing:

$ ctest

Final executable should be called as:

$ ncdfToFoam mesh000.nc

where the present working directory contains:

|-- mesh000.nc
   
|-- mesh001.nc 
   
|-- result

    |-- mesh000sol.nc
   
    |-- mesh001sol.nc

|-- constant

|-- system
    
    |-- controlDict

    |-- fvSolution

The program will generate polyMesh in constant

|-- constant
    
    |-- polyMesh

        |-- points

        |-- faces

        |-- boundary

        |-- owner

        |-- neighbour
