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.

Returns: IRResultType
