Detailed Description

To prescribe various types of data by an algebraic expression. Data may consist in boundary conditions, forces, tractions, fluxes, initial condition. All these data types can be defined through an enumerated variable.

Constructor & Destructor Documentation

Prescription	(	Mesh &	mesh,
		const string &	file
	)

Constructor that gives an instance of class Mesh and the data file name. It reads parameters in VDF Format from this file.

Parameters:

[in]	mesh	Mesh instance
[in]	file	Name of VDF file

int get	(	int	type,
		Vect< double > &	v,
		double	time = 0,
		size_t	dof = 0
	)

Read data in the given file and stores in a Vect instance for a chosen DOF. The input value type determines the type of data to read.

Parameters:

[in]	type	Type of data to seek. To choose among the enumerated values: BOUNDARY_CONDITION : Read values for (Dirichlet) boundary conditions BOUNDARY_FORCE : Read values for boundary force (Neumann boundary condition). The values TRACTION and FLUX have the same effect. BODY_FORCE : Read values for body (or volume) forces. The value SOURCE has the same effect. POINT_FORCE : Read values for pointwise forces INITIAL_FIELD : Read values for initial solution
[in,out]	v	Vect instance that is instantiatd on input and filled on output
[in]	time	Value of time for which data is read (Default value is 0).
[in]	dof	DOF to store (Default is 0: All DOFs are chosen).
