Detailed Description

template<EulerModel model>
struct DNDS::Euler::EulerEvaluatorSettings< model >::FrameConstRotation

Constant-rotation reference frame settings.

When enabled, the solver transforms the governing equations into a non-inertial frame rotating at a constant angular velocity about the specified axis through the specified center.
