Detailed Description

template<size_t ThermodynamicDim>
class grmhd::AnalyticData::SpecInitialData< ThermodynamicDim >

Hydro initial data generated by SpEC.

This class loads numerical data written out by the SpEC initial data solver. It uses the spec::Exporter linked in from SpEC to interpolate to arbitrary grid points. The coordinates are assumed to be in SpEC's "grid" frame. We interpolate the following quantities:

"g": spatial metric
"K": (lower) extrinsic curvature
"Lapse": lapse
"Shift": (upper) shift
"BaryonDensity": rest mass density
"u_i": lower spatial four-velocity

The remaining hydro quantities are computed from the interpolated data and the equation of state. The magnetic field is set to zero and the electron fraction is set to a constant read from the input file.
