Level Set Model
The Level Set Model node adds the following transport equation governing a level set function
and provides the options to define the associated level set parameters and the velocity field.
Level Set Parameters
Enter a value or expression for the Reinitialization parameter γ (SI unit: m/s). The default is 1 m/s.
Enter a value or expression for the Parameter controlling interface thickness els (SI unit: m). The default expression is ls.hmax/2, which means that the value is half of the maximum mesh element size in the region through which the interface passes.
Convection
Enter values or expressions for the components (u, v, and w in 3D, for example) of the Velocity field u (SI unit: m/s). The applied velocity field transports the level set function through convection.
