◆ PrescribeRhsValues() [1/2]

template<typename LAI >

static void geosx::FieldSpecificationEqual::PrescribeRhsValues	(	typename LAI::ParallelVector &	rhs,
		localIndex const	num,
		globalIndex *const	dof,
		real64 *const	values
	)

inlinestatic

Function to add some values of a vector.

Parameters

rhs	A ParallelVector object.
num	The number of values in `rhs` to replace
dof	A pointer to the global DOF to be replaced
values	A pointer to the values corresponding to `dof` that will be added to `rhs`.

Definition at line 505 of file FieldSpecificationOps.hpp.

◆ PrescribeRhsValues() [2/2]

template<typename POLICY >

static void geosx::FieldSpecificationEqual::PrescribeRhsValues	(	arrayView1d< real64 > const &	rhs,
		arrayView1d< globalIndex const > const &	dof,
		globalIndex const	dofRankOffset,
		arrayView1d< real64 const > const &	values
	)

inlinestatic

Function to add some values of a vector.

Template Parameters

POLICY the execution policy to use when setting values

Parameters

rhs	the target right-hand side vector
dof	a list of global DOF indices to be set
dofRankOffset	offset of dof indices on current rank
values	a list of values corresponding to `dof` that will be added to `rhs`.

Definition at line 528 of file FieldSpecificationOps.hpp.

◆ SpecifyFieldValue() [1/2]

template<typename LAI >

static void geosx::FieldSpecificationEqual::SpecifyFieldValue	(	globalIndex const	dof,
		typename LAI::ParallelMatrix &	matrix,
		real64 &	rhs,
		real64 const	bcValue,
		real64 const	fieldValue
	)

inlinestatic

Function to apply a Dirichlet like boundary condition to a single dof in a system of equations.

Parameters

[in]	dof	The degree of freedom that is to be set.
[in,out]	matrix	A ParallelMatrix object: the system matrix.
[out]	rhs	The rhs contribution resulting from the application of the BC.
[in]	bcValue	The target value of the Boundary Condition
[in]	fieldValue	The current value of the variable to be set.

This function clears the matrix row for the specified dof, sets the diagonal to some appropriately scaled value, and sets rhs to the negative product of the scaled value of the diagonal and the difference between bcValue and fieldValue.

Note: This function assumes the user is doing a Newton-type nonlinear solve and will negate the rhs vector upon assembly. Thus, it sets the value to negative of the desired update for the field. For a linear problem, this may lead to unexpected results.

◆ SpecifyFieldValue() [2/2]

static GEOSX_HOST_DEVICE void geosx::FieldSpecificationEqual::SpecifyFieldValue	(	globalIndex const	dof,
		globalIndex const	dofRankOffset,
		CRSMatrixView< real64, globalIndex const > const &	matrix,
		real64 &	rhs,
		real64 const	bcValue,
		real64 const	fieldValue
	)

inlinestatic

Function to apply a Dirichlet like boundary condition to a single dof in a system of equations.

Parameters

[in]	dof	The degree of freedom that is to be set.
[in]	dofRankOffset	offset of dof indices on current rank
[in,out]	matrix	the local part of the system matrix
[out]	rhs	The rhs contribution resulting from the application of the BC.
[in]	bcValue	The target value of the Boundary Condition
[in]	fieldValue	The current value of the variable to be set.

This function clears the matrix row for the specified dof, sets the diagonal to some appropriately scaled value, and sets rhs to the negative product of the scaled value of the diagonal and the difference between bcValue and fieldValue.

Note: This function assumes the user is doing a Newton-type nonlinear solve and will negate the rhs vector upon assembly. Thus, it sets the value to negative of the desired update for the field. For a linear problem, this may lead to unexpected results.
