warp.fem.field.TestField#

class warp.fem.field.TestField(space, space_restriction)[source]#

Field defined over a space restriction that can be used as a test function.

In order to reuse computations, it is possible to define the test field using a SpaceRestriction defined for a different value type than the test function value type, as long as the node topology is similar.

Parameters:
__init__(space, space_restriction)[source]#
