  This paper introduces SuperVoxHenry, an inductance extraction simulator for
analyzing voxelized superconducting structures. SuperVoxHenry extends the
capabilities of the inductance extractor VoxHenry for analyzing the
superconducting structures by incorporating the following enhancements. 1.
SuperVoxHenry utilizes a two-fluid model to account for normal currents and
supercurrents. 2. SuperVoxHenry introduces the Tucker decompositions to reduce
the memory requirement of circulant tensors as well as the setup time of the
simulator. 3. SuperVoxHenry incorporates an aggregation-based algebraic
multigrid technique to obtain the sparse preconditioner.
