Backward Compatibility with Version 4.4

Inlet Feature

The old inlet features still exist, but have been excluded from the physics context menu. Old models retain old Inlet features, but adding a new Inlet feature comes with the new functionality. Old Model Java® files create Inlet features of the old types. The Normal stress condition can still be prescribed on inlets using an Open Boundary or a Boundary Stress feature.

New Names For Mass Transport Interfaces

Running Model Java® files from previous versions may fail due to the new default names in the Transport of Diluted Species and Transport of Concentrated Species interfaces. This can be avoided by adding a command that specifies the identifier in accordance with the Name of the interface. For example, when creating a Transport of Concentrated Species interface using the old name (chcs):

model.physics().create("chcs", "ConcentratedSpecies", "geom1",

                       new String[][]{{"wO2", "wH2O", "wN2"}});

Add the following line to specify the identifier accordingly:

model.physics("chcs").identifier("chcs");

Wall Distance Equation

The old Continuity node is still included in the interface but is excluded from the feature list. Hence, old models retain their old Continuity node when opened in version 5.2a and old Model Java®files are fully backward compatible.

Euler-Euler Model, Laminar Flow

The results from models using the Euler-Euler Model, Laminar Flow interface may differ in version 5.2a due to the more general formulation for the viscous stress in the momentum equation for the dispersed phase. The behavior in the old formulation may be reproduced by dividing the dispersed phase viscosity, μD, by the variable ee.phidPos.
