Adaptive time stepping in quench simulation for superconducting magnets

Thermo-Hydraulic Calculations on W7-X Coils for Updated Quench Detection Parameters

“…The active error control makes the time step adaption more reliable and is governed by the value of the tolerance parameter. Each time step is iterated until the error is smaller than the desired tolerance or until it reaches the assumed minimum step value and cannot shrink anymore [10]. Finally a tolerance of 0.03 was applied as standard.…”
