field : Field instance
The field defining the approximation.
coors : array
The physical coordinates.
strategy : str, optional
The strategy for finding the elements that contain the
coordinates. Only ‘kdtree’ is supported for the moment.
close_limit : float, optional
The maximum limit distance of a point from the closest
element allowed for extrapolation.
cache : Struct, optional
To speed up a sequence of evaluations, the field mesh, the inverse
connectivity of the field mesh and the KDTree instance can be cached as
cache.mesh, cache.offsets, cache.iconn and
cache.kdtree. Optionally, the cache can also contain the reference
element coordinates as cache.ref_coors, cache.cells and
cache.status, if the evaluation occurs in the same coordinates
repeatedly. In that case the KDTree related data are ignored.
verbose : bool
If False, reduce verbosity.
