double relative() const

Estimated error relative to the estimated exact energy norm.

Public attributes

elementSquared

std::vector<double> elementSquared

Squared energy-norm error per tetrahedron: the stress error times the strain error it causes, integrated over the element (J).

double errorSquared

energySquared

double energySquared

Squared energy norm of the finite element solution: twice its strain energy (J).
