		KERNEL_TYPE const &	kernelComponent
	)

static

Kernel Launcher.

Template Parameters

POLICY	The RAJA policy to use for the launch.
NUM_QUADRATURE_POINTS	The number of quadrature points per element.
KERNEL_TYPE	The type of Kernel to execute.

Parameters

numElems	The number of elements to process in this launch.
kernelComponent	The instantiation of KERNEL_TYPE to execute.

Returns: The maximum residual contribution.

This is a generic launching function for all of the finite element kernels that follow the interface set by KernelBase.

ExplicitSmallStrain Description

Copy of the KernelBase::kernelLaunch function without the exclusion of ghost elements.

		localIndex const	q,
		StackVariables &	stack
	)		const

inline

Performs a state update at a quadrature point.

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.
q	The quadrature point index.
stack	The StackVariable object that hold the stack variables.

KernelBase::quadraturePointKernel() Description

The operations found here are the mapping from the support points to the quadrature point, calculation of gradients, etc. From this data the state of the constitutive model is updated if required by the physics package.

ExplicitSmallStrain Description

Calculates the shape function derivatives, and the strain tensor. Then calls the constitutive update, and also performs the integration of the stress divergence, rather than using the dedicated component function to allow for some variable reuse.

◆ setup()

template<typename SUBREGION_TYPE , typename CONSTITUTIVE_TYPE , typename FE_TYPE >

GEOS_HOST_DEVICE void geos::solidMechanicsLagrangianFEMKernels::ExplicitFiniteStrain< SUBREGION_TYPE, CONSTITUTIVE_TYPE, FE_TYPE >::setup	(	localIndex const	k,
		StackVariables &	stack
	)		const

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.

Copies the primary variable, and position into the local stack array.

staticconstexpr

Maximum number of nodes per element, which is equal to the maxNumTestSupportPointPerElem and maxNumTrialSupportPointPerElem by definition. When the FE_TYPE is not a Virtual Element, this will be the actual number of nodes per element.
