relative_truncation_error()

template<typename VectorType , size_t Dim>

std::array< double, Dim > PowerMonitors::relative_truncation_error	(	const VectorType &	tensor_component,
		const Mesh< Dim > &	mesh
	)

The relative truncation error in each logical direction of the grid.

This overload is intended for visualization purposes only. It takes a tensor component as input, so it can be used as a kernel to post-process volume data with Python bindings (see TransformVolumeData.py).
