Description🔗
The alphaContactAngle
is a boundary condition that provides
contact-angle boundary condition for multi-phase interface-capturing
simulations. It is used in conjunction with multiphaseSystem
.
Usage🔗
The condition requires entries in both the boundary and field files.
Boundary file🔗
<patchName>
{
type patch;
...
}
Field file🔗
<patchName>
{
// Mandatory entries
type alphaContactAngle;
thetaProperties
(
(<phase1> <phase2>) <scalar1> <scalar2> <scalar3> <scalar4>
(<phase3> <phase2>) <scalar1> <scalar2> <scalar3> <scalar4>
...
);
// Inherited entries
