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.

		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.

The ImplcitNewmark kernel adds the calculation of the inertia damping, jacobian and residual contributions.

inline

Copy global values from primary field to a local stack array.

For the ImplicitNewmark implementation, global values from the velocity predictor, and the incremental displacement predictor are placed into element local stack storage.
