+* The ``enable`` parameter is set to ``true`` when at least one temperature-dependent stasis constraint should be applied.
 
 * The ``number of constraints`` parameter is an integer representing the number of constraints that will be applied. It is used in multiphase (VOF) simulations to apply different constraints to each fluid. Only one constraint per fluid can be imposed. Each constraint comes with its own subsection (starting with number ``0``) containing its own set of parameters as detailed below.
