class geos::finiteElement::SparsityKernelBase< SUBREGION_TYPE, CONSTITUTIVE_TYPE, FE_TYPE, NUM_DOF_PER_TEST_SP, NUM_DOF_PER_TRIAL_SP >

Define the base interface for implicit finite element kernels.

Define the base interface for finite element kernels.

Template Parameters

SUBREGION_TYPE	The type of subregion that the kernel will act on.
CONSTITUTIVE_TYPE	The type of constitutive model present in the subregion.
NUM_TEST_SUPPORT_POINTS_PER_ELEM	The number of test space support points per element.
NUM_TRIAL_SUPPORT_POINTS_PER_ELEM	The number of trial space support points per element.
NUM_DOF_PER_TEST_SP	The number of DOF per test support point.
NUM_DOF_PER_TRIAL_SP	The number of DOF per trial support point.

General KernelBase Description

KernelBase defines an interface for implementing finite element kernels that will be callable by the family of kernel launch functions. Specific physics kernels may or may not derive from KernelBase, but must follow the same interface in order to be callable from the generic launching functions.

The template parameters of KernelBase should be duplicated as part of the interface, EXCEPT for NUM_DOF_PER_TEST_SP and NUM_DOF_PER_TRIAL_SP. These values should be set internally by the physics solver since each physics discretization will have a constant intrinsic value for these quantities. For example, when solving or the heat equation with scalar temperature as the primary variable at the support point, these will have a value of 1. In contrast, when solving a solid mechanics problem, with vector displacement as the primary variable at the support point, these will have a value of 3. Note that the interface provided by geos::finiteElement::RegionBasedKernelApplication will construct a kernel assuming only the first 4 template arguments.

SparsityKernelBase Description

Provide common kernels for generation of CRS Sparsity patterns.

		StackVariables &	stack
	)		const

inline

Performs the complete phase for the kernel.

Template Parameters

STACK_VARIABLE_TYPE The type of StackVariable that holds the stack variables. This is most likely a defined in a type that derives from KernelBase.

Parameters

k	The element index.
stack	The StackVariable object that hold the stack variables.

Returns: The maximum contribution to the residual.

KernelBase::complete() Description

The operations typically found in complete are the mapping of the local Jacobian and Residual into the global Jacobian and Residual.

In this implementation, only the matrix values are inserted, making this implementation appropriate for generating the sparsity pattern.
