Detailed Description

template<size_t Dim, typename TensorTags>
class amr::Criteria::Constraints< Dim, TensorTags >

Refine the grid towards the target constraint violation.

• If any constraint is above the target value, the element will be p-refined.
• If all constraints are below the target times the "coarsening factor" the element will be p-coarsened.

This criterion is based on Sec. 6.1.4 in [198] .

If the coarsening factor turns out to be hard to choose, then we can try to eliminate it by projecting the variables to a lower polynomial order before computing constraints, or something like that.

Template Parameters

Dim	Spatial dimension of the grid
TensorTags	List of tags of the constraints to be monitored. These must be tensors of rank 2 or higher. The first index must be a lower spatial index that originates from a derivative.
