Zero Gradient Family of Outlet Boundary Conditions

From mathematical point of view, zero gradient value boundary conditions are Neumann boundary conditions.

At the outlet, for all the quantities (except pressure) the typical choice is zeroGradient based boundary condition.

Standard Visual Postprocessing - Paraview

Standard postprocessing tool with OpenFOAM is Paraview software. When case is multi-region the region must be specified, when opening with paraFoam:

# paraFoam -region rotor

Or, another option is to create .OpenFOAM files and then open regions (.OpenFOAM format) in standard Paraview:

# paraFoam -touchAll
# paraview

Or, another option is to create .foam file and then open in standard Paraview:

# touch .foam
# paraview .foam
