openFuelCell2

What tutorial cases are provided?

For each application, which is able to be simulated by the code, a tutorial case is provided.

• conjugate heat transfer: CHT
• Low temperature PEM electrolyzer: PEMEC
• Low temperature PEM fuel cell: PEMFC
• High temperature PEM electrolyzer: HTPEMEC
• High temperature PEM fuel cell: HTPEMFC
• Hydrogen pump: hydrogenPump
• Solid oxide fuel cell: SOFC
• Solid oxide electrolyzer: SOEC

Each tutorial:

• Common OpenFoam cases structure:
  • 0.orig : Backup of 0
  • constant
  • system
  • Makefile: To generate mesh, run the solver, view the solution…
  • Allclean: To clean up the tutorial
  • parallel.sh: To generate processors for parallel simulation
  • preprocessing.sh: To generate mesh for serial simulation

How to run the tutorial cases?

• In serial

    # Generate the meshes with 'blockMesh'
    make mesh
    # or Generate the meshes with 'salome'
    # make salomeMesh
    # Run in serial
    make srun
  

• In parallel

    # Generate the meshes with 'blockMesh'
    make mesh
    # or Generate the meshes with 'salome'
    # make salomeMesh
    # Edit values of 'nx' and 'ny' in constant/cellProperties
    export NPROCS=nx*ny # (value of 'nx' times 'ny')
    # Generate the cellID
    # For manual decomposition
    make decompose
    # Decomposition for multiple regions
    make parallel
    # Run in parallel
    make run  #( the value of 'nx' times 'ny' needs to be changed in 'Makefile')
    # or
    # mpirun -np nx*ny fuelCell0Foam -parallel -fileHandler collated | tee log.run
  

To view the result:

• In serial

  • Residual plot

    make plot
    # or gnuplot ResidualPlot
    

  • Simulation results

    # Convert openfoam result to vtk
    make view
    # execute paraview to view
    paraview
    

• In parallel

  • Residual plot

    # plot the residuals with gnuplot
    make plot
    # or gnuplot ResidualPlot
    

  • Simulation results

    # Reconstruct the mesh
    make reconstruct
    # Convert the results to vtk
    make view
    # Execute paraview to view
    paraview
