◆ quadraturePointKernel()

template<typename SUBREGION_TYPE , typename CONSTITUTIVE_TYPE , typename FE_TYPE >

GEOSX_HOST_DEVICE GEOSX_FORCE_INLINE void geosx::SolidMechanicsLagrangianFEMKernels::ExplicitFiniteStrain< SUBREGION_TYPE, CONSTITUTIVE_TYPE, FE_TYPE >::quadraturePointKernel	(	localIndex const	k,
		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 >

GEOSX_HOST_DEVICE GEOSX_FORCE_INLINE void geosx::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.
