Detailed Description

Vacuum 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:

• "Nid_g": spatial metric
• "Nid_K": (lower) extrinsic curvature
• "Nid_N": lapse
• "Nid_Shift": (upper) shift
