Detailed Description

template<typename Frame>
struct control_system::QueueTags::ShiftyQuantity< Frame >

Holds a quantity that's similar to the shift, but isn't the shift, on the ExcisionSurface.

Details

This holds

\begin{equation}\beta^i \frac{\partial x^\hat{i}}{\partial x^i} = \hat{beta}^\hat{i} + \frac{\partial x^\hat{i}}{\partial t} \end{equation}

where hatted quantities are in the distorted frame and non-hatted quantities are in the grid frame.
