示例1: add_level
# 需要导入模块: from level import Level [as 别名]
# 或者: from level.Level import restrict [as 别名]
def add_level(self, feval, sdc, interpolate=None, restrict=None):
"""Add a level to the PFASST hierarchy.
:param feval: implicit/explicit function evaluator (instance
of :class:`pfasst.feval.FEval`)
:param sdc: implicit/explicit SDC sweeper (instance
of :class:`pfasst.sdc.SDC`)
:param interpolate: interpolate from coarser level to this
level (callable)
:param restrict: restrict from this level to coarser level
(callable)
Levels should be added from finest (level 0) to coarest.
The *interpolate* callable is called as::
>>> interpolate(yF, yG, fevalF=fevaF, fevalG=fevalG, **kwargs)
and should interpolate the coarse y values *yG* that
correspond to the coarse evaluator *fevalG* to the fine y
values *yF* that correspond to the fine evaluator *fevalF*.
The (flattened) result should be stored in *yF*.
The *restrict* callable is called as::
>>> restrict(yF, yG, fevalF=fevalF, fevalG=fevalG, **kwargs)
and should restrict the fine y values *yF* that correspond to
the fine evaluator *fevalF* to the coarse y values *yG* that
correspond to the coarse evaluator *fevalG*. The (flattened)
result should be stored in *yG*.
