A Rotating frame property has been added to the Physical Model properties in the Creeping Flow, Laminar Flow, and Brinkman Equations interfaces. When selected, the velocity field is defined relative to a rotating frame by including the fictitious Coriolis, centrifugal, and Euler forces in the momentum equation and a global Rotating Frame feature, with settings for the Axis of rotation, Rotation speed, and Rotational direction, is automatically added to the physics interface.

In the Free Surface and Fluid–Fluid Interface features, the Surface tension coefficient list has the new option Library coefficient, liquid mixture/gas interface with a selection of predefined binary liquid mixtures. When a Transport of Diluted Species interface is active in the component, the appropriate interface selection can alternatively be selected to apply the surface tension values of each corresponding species, which applies the concentration from the Transport of Diluted Species interface.

The Free and Porous Media Flow Coupling has a new option to Include pressure jump across free–porous boundary.

When the Flow model in the Porous Medium feature is set to Non-Darcian, the Porous Matrix subnode has a new option to specify a user-defined Inertial resistance coefficient.

An error in the implementation of the Ternary Phase Field interface’s Wetted Wall feature, which resulted in the wrong contact angle between the phases A and B when the three surface-tension coefficients were not identical, has been corrected. As a result, the definitions of the contact angles now agree with the figure shown in the feature’s Settings window.
