High-temperature superconductors (HTS) have the potential to enable magnetic fields beyond current limits of low-temperature in applications like accelerator magnets. However, design HTS-based magnets requires computationally demanding transient multi-physics simulations with highly non-linear material properties. To reduce solution time, we propose using Parareal (PR) for parallel-in-time magneto-thermal simulation based on HTS, particularly, no-insulation coils without turn-to-turn insulation. We extending classical PR method automatically find a time partitioning first coarse adaptive propagator. The proposed is shown computing when fine engineering tolerances are required despite nonlinear character problem. full software stack used open-source.
