Detailed Description

Abstract base class representing Lagrangian-Eulerian (moving) material interfaces. Its typical use to model moving interface (such as free surface) in a fixed-grid methods (as typically used in CFD). The basic tasks are representation of interface and its updating.

Parameters

ir	Input record to initialize from.
priority	Priority of the input record. This is used to determine the order of initialization
