warp.fem.NonconformingField

class warp.fem.NonconformingField(domain, field, background=0.0)

Field defined as the map of a DiscreteField over a non-conforming geometry.

Parameters:

• domain (GeometryDomain) – The new domain over which the nonconforming field will be evaluated

• field (DiscreteField) – Nonconforming discrete field

• background (Any) – Uniform value or domain-conforming field determining the value outside of the geometry of definition of field

__init__(domain, field, background=0.0)

Parameters:

• domain (GeometryDomain)

• field (DiscreteField)

• background (Any)
