3DEC Commands and FISH

The 3DEC model consists of blocks and that may or may not be discretized into zones. The interaction between the surfaces of two blocks is defined by a mechanical interaction that is composed of a single contact (joint) divided into subcontacts to produce an accurate solution.

Structural support may be provided by structural elements such as cables and liners.

Flow planes may also be present to simulate fluid flow in joints.
