We define an index allowing to quickly judge if the mesh is in agreement with the metric field.
Let us note
the length of the edge in the metric.
The efficiency index of a mesh is defined as the exponentiel of the mean between the difference with of all the lengths normalized by the number of mesh edges.
Let us call this index:
with si and
if and the number of mesh edges.
