pure virtual |
Represents a function prescribed on the boundary. Gets the boundary point coordinate as well as the normal and tangential vectors.
[in] | x | x-coordinate of the point where the value is evaluated. |
[in] | y | y-coordinate of the point where the value is evaluated. |
[in] | n_x | the x-component of the unit outer normal. |
[in] | n_y | the y-component of the unit outer normal. |
[in] | t_x | the x-component of the tangent(perpendicular to normal). |
[in] | t_y | the y-component of the tangent(perpendicular to normal). |
Implemented in Hermes::Hermes2D::DefaultEssentialBCNonConst< Scalar >, and Hermes::Hermes2D::DefaultEssentialBCConst< Scalar >.
