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.
