Detailed Description

template<class F = Real>
class estimator::ExactEstimator< F >

Abstract class representing the explicit residual a posteriori error estimator.

At the moment just one underlying space is supported, i.e. with that robin conditions cannot be handeled for the residuals, atm

template<class G , class H >

void estimator::ExactEstimator< F >::addErrorContr ( const concepts::ElementFormula< G > *  efrm, const concepts::ElementFormula< H > *  afrm, Real  s = 1.0, const concepts::ElementFormula< F > *  w = 0  )

inline

Sets individual norm contributions up to now everything in L2 norm.

example 1) efrm = Grad(u), afrm = Grad(u_{hp}), w = 0 , s = 1.0 implies norm contribution || Grad(u) - Grad[u_{hp}] ||_{L^2(K)} on each element K.

example 2) efrm = u, afrm = u_{hp} w = ParsedFormula("(1/sqrt(x^2+y^2))") s = lambda implies the contribution lambda * || w * (u_{hp}-u) ||_{L^2(K)} on each element K where u_{hp} is the approximate solution
