First, if you want to find the list of boundary conditions on a specific solver do this: solverName -listVectorBCs solverName -ListScalarBCs To get info about a specific boundary condition use foamInfo NameOfBC The complete list of boundary condition types in OpenFOAM are listed here: $FOAM_SRC/finiteVolume/fields/fvPatchFields/basic Second, current boundary conditions for pressure are as follows. They […]

Pressure in OpneFOAM has two different dimensions in the solvers. In compressible solvers, the dimension is kg/ms^2 (N/m^2) and in incompressible solvers, it is normalized by constant fluid dnesity i.e. m^2/s^2. Regarding the absolute pressure or relative pressure, it also dependent to the type of the solver. For incompressible solvers, the relative pressure is used
