BreakMeshByElementGenerator

Break all element-element interfaces in the specified subdomains.

Overview

The BreakMeshByElementGenerator is used to break all element-element interfaces in specified subdomains. All element-element interfaces are grouped into a boundary of user's choice.

Example input syntax

In this example input file, we break all element-element interfaces in subdomains 1 and 2.
