Support data file for codes for integral method to calculate ac loss in superconducting tapes

This is a supplementary file for the codes (to be) published on https://www.htsmodelling.com/?page_id=748#pyCalvin, which model superconducting tapes under arbitrary field whilst carrying transport current, and which support [1]. The file here is the time derivative of magnetic vector potential A, evaluated at different locations and time instants, obtained from a COMSOL file of an electrical machine without superconducting tapes that are modelled by the integral method.
