WVFlowComponent

Orthogonal solution group

---

Overview

Each degree-of-freedom in the model is associated with an analytical solution to the equations of motion. This class groups together solutions of a particular type and provides a mapping between their analytical solutions and their numerical representation.

Perhaps the most complicate part of the numerical implementation is the indexing—finding where each solution is represented numerically. In general, a solution will have some properties, e.g., (kMode,lMode,jMode,phi,A,omegasign) which will have a primary and conjugate part, each of which might be in two different matrices.
