Detailed Description

Numeric initial data loaded from volume data files.

This class can be factory-created in the input file to start an evolution from numeric initial data. It selects the hydro variables to load from the volume data files and allows to choose constant values for some of them.

Where the density is below the DensityCutoff the fluid variables are set to vacuum (zero density, pressure, energy and velocity, and unit Lorentz factor). To evolve the initial data, an atmosphere treatment is likely required to fix the value of the fluid variables in these regions.
