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 geosx::finiteElement::RegionBasedKernelApplication will construct a kernel assuming only the first 4 template arguments.
ImplicitKernelBase Description
Provides a common base for kernels that require the assembly of a system of equations. The types required to assemble the system, such as DOF information, the Matrix and Vector object, etc., are declared and set here.

Constructor & Destructor Documentation
◆ ImplicitKernelBase()
|
inline |
Constructor.
- Parameters
-
nodeManager Reference to the NodeManager object. edgeManager Reference to the EdgeManager object. faceManager Reference to the FaceManager object. inputDofNumber The dof number for the primary field. rankOffset dof index offset of current rank inputMatrix Reference to the Jacobian matrix. inputRhs Reference to the RHS vector. Constructor. elementSubRegion Reference to the SUBREGION_TYPE(class template parameter) object. inputConstitutiveType The constitutive object. finiteElementSpace Placeholder for the finite element space object, which currently doesn't do much.

Member Function Documentation
◆ setup()
|
inline |
Performs the setup 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.
KernelBase::setup() Description
The operations typically found in setup are thing such as the collection of global data into local stack storage.
ImplicitKernelBase::setup() Description
In this implementation, the element local Row and Column DOF stack arrays are filled for when we fill the global matrix and rhs.
- Note
- This seems like a waste of register space. We should do this in complete() unless we actually need these dof somewhere else in the kernel.
