Detailed Description
class Dune::Functions::DiscreteGlobalBasisFunctionDerivative< DGBF >::LocalFunction
local function evaluating the derivative in reference coordinates
Note that the function returns the derivative with respect to global coordinates even when the point is given in reference coordinates on an element.
Member Function Documentation
◆ bind()
|
inline |
Bind LocalFunction to grid element.
You must call this method before operator()
and after changes to the coefficient vector.
◆ operator()()
|
inline |
Evaluate this local-function in coordinates x
in the bound element.
The result of this method is undefined if you did not call bind() beforehand or changed the coefficient vector after the last call to bind(). In the latter case you have to call bind() again in order to make operator() usable.
Note that the function returns the derivative with respect to global coordinates even when the point is given in reference coordinates on an element.
