Detailed Description

An abstract class defining the interface for discretized essential boundary condition definitions (essential boundary condition, i.e. boundary conditions on the degrees-of-freedom).

The essential boundary condition is defined by the constraint g(u,t) = 0 or g(u,t) <= 0 where u is the current dof, g is a nonlinear function of the from R(nb_dof) X R to R(m) and t is the time.

Member Enumeration Documentation

Type

enum b2000::EssentialBoundaryCondition::Type

The different types of essential boundary conditions.

Enumerator
none	An empty essential boundary condition.
constant_value	The values of g do not depend on the dof's. Thus g is if the form: g = d.
constant_derivative	The derivatives of g do not depend on the dof's. Thus g is of the form g = Gu + d.
noconstant_derivative	The derivatives of g depend on the dof's.

get_size()

virtual size_t b2000::EssentialBoundaryCondition::get_size ( const bool  linear )

pure virtual

Returns

The number of constraints.

get_type()

virtual Type b2000::EssentialBoundaryCondition::get_type ( ) const

pure virtual

Returns

The type of the essential boundary condition (how the boundary condition varies with the dof's).
