Detailed Description

This class implements the (modified) Ginzburg Landau potential, which is given by

\[ \mathcal{W}(x) = \begin{cases} (1+x)^2, & x \le -1, \\ \frac14 (1-x^2)^2, & |x| \leq 1, \\ (1-x)^2, & x > 1. \end{cases} \]

Constructor & Destructor Documentation

GLPotential::GLPotential ( )

Constructor. Just initalize the members

Member Function Documentation

double GLPotential::operator() ( const double  x) const

Derivative: $\mathcal{W}'(x)$.

Member Data Documentation

const double GLPotential::max_second_deriv [private]

Maximum of the second derivative: $\sup_{x \in \mathbb{R}} |\mathcal{W}''(x)|$.

Definition at line 91 of file Material.h.

const double GLPotential::A

The value of the maximum of the second derivative is known beforehands, and so it is the value of the stabilization parameter. Thus, we make it a constant.
