示例1: get_evaluate_cache
# 需要导入模块: from sfepy.base.base import Struct [as 别名]
# 或者: from sfepy.base.base.Struct import normals1 [as 别名]
def get_evaluate_cache(self, cache=None, share_geometry=False,
verbose=False):
"""
Get the evaluate cache for :func:`Variable.evaluate_at()
<sfepy.discrete.variables.Variable.evaluate_at()>`.
Parameters
----------
cache : Struct instance, optional
Optionally, use the provided instance to store the cache data.
share_geometry : bool
Set to True to indicate that all the evaluations will work on the
same region. Certain data are then computed only for the first
probe and cached.
verbose : bool
If False, reduce verbosity.
Returns
-------
cache : Struct instance
The evaluate cache.
