protectedvirtual

Given a spectral/hp approximation $u^{\delta}(\boldsymbol{x})$ evaluated at the quadrature points (which should be contained in m_phys), this function calculates the $L_2$ error of this approximation with respect to an exact solution. The local distribution of the quadrature points allows an elemental evaluation of this operation through the functions StdRegions::StdExpansion::L2.

The exact solution, also evaluated at the quadrature points, should be contained in the variable m_phys of the ExpList object Sol.

Parameters
SolAn ExpList, containing the discrete evaluation of the exact solution at the quadrature points in its array m_phys.
Returns
The $L_2$ error of the approximation.
