# 13. POD

Proper Orthogonal Decomposition (POD) and Explicit Control Modes (ECM) should have almost the same name according to the rule “the name of a method should describe what is done, not how it is done” A difference from ECM is that POD does not require a coarse finite element mesh. POD is intended for explicit analyses in which the time step is too small, and constructing a coarser mesh for ECM is unfeasible.

Explicit only

POD is an experimental analysis technique.
