Detailed Description

template<size_t VolumeDim, typename Fr>
class gh::ConstraintDamping::Constant< VolumeDim, Fr >

A constant function: \(f = C\).

Details

Input file options are: Value \(C\). The function takes input coordinates of type tnsr::I<T, VolumeDim, Fr>, where T is e.g. double or DataVector, Fr is a frame (e.g. Frame::Inertial), and VolumeDim is the dimension of the spatial volume.
