constraint_coeff()

procedure m_mform_matrix::massmatrix::constraint_coeff

(

class(massmatrix), intent(in)

this

)

Coefficient for the imposing a linear constraint on the mass matrix by means of a projection operator.

That is, when mode=CONSTRAINT_PROJECTION is used, the following matrix is constructed: P^T * M * P + \gamma * (I - P)^T M * (I - P), where P is the projection operator and M is the mass matrix. This function provides the coefficient \gamma.

Parameters

[in]

this

The MassMatrix object for which to compute the coefficient

Returns

The coefficient \gamma

init()

procedure m_mform_matrix::massmatrix::init	(	class(massmatrix), intent(inout)	this,
		type(mformspace), intent(in)	space,
		class(coordtransformabstract), intent(in), optional	coord_transform,
		procedure(user_function_3d_interface), optional	userfun,
		procedure(user_function_3d_mat_interface), optional	userfun_mat,
		integer, intent(in), optional	n_quad_extra )

Initialize the mass matrix for the given m-form space.

Parameters

[in,out]	this	The MassMatrix object to initialize
[in]	space	The MFormSpace for which to initialize the mass matrix
[in]	coord_transform	_(optional)_ The coordinate transformation associated with the m-form space
[in]	userfun	_(optional)_ A user-defined function to used to scale the inner product that defines the mass matrix
[in]	userfun_mat	_(optional)_ A user-defined matrix-valued function to used to scale the inner product that defines the mass matrix
[in]	n_quad_extra	_(optional)_ The number of extra quadrature points to use for the mass matrix on top of those needed for the exact integration of the product of the B-spline basis functions
