Detailed Description

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

Refine the grid towards the target truncation error.

If any tensor component has a truncation error above the target value, the element will be p-refined.
If all tensor components still satisfy the target even with one mode removed, the element will be p-coarsened.

For details on how the truncation error is computed see PowerMonitors::truncation_error.

Template Parameters

Dim	Spatial dimension of the grid
TensorTags	List of tags of the tensors to be monitored
