◆ evaluate()

void MAST::LevelSetPerimeter::evaluate ( )

virtual

this is the abstract interface to be implemented by derived classes.

This method calculates the quantity $ q(X, p) $ . This is provided as an interface since some quantities requires evaluation of all inputs before the final quantity can be calculated. So, the user can call this routine on each element before requesting the output values using either output_for_elem() or output_total().

◆ evaluate_sensitivity()

void MAST::LevelSetPerimeter::evaluate_sensitivity ( const MAST::FunctionBase & f )

this evaluates all relevant sensitivity components on the element.

This is only done on the current element for which this object has been initialized.

◆ output_derivative_for_elem()

virtual void MAST::LevelSetPerimeter::output_derivative_for_elem ( RealVectorX & dq_dX )

◆ output_for_elem()

Real MAST::LevelSetPerimeter::output_for_elem ( )

virtual

Returns: the output quantity value contribution for the present element for which this object has been initialized. This does not make sense for some output quantities that are defined as averaged over a domain, example the p-norm of the stress (see MAST::StressStrainOutputBase). For such cases, the output_total must be called.

Implements MAST::OutputAssemblyElemOperations.

Definition at line 83 of file level_set_perimeter_output.cpp.

◆ output_sensitivity_for_elem()

Real MAST::LevelSetPerimeter::output_sensitivity_for_elem ( const MAST::FunctionBase & p )

virtual

$\frac{\partial q(X, p)}{\partial p}$
with respect to parameter . This returns the quantity evaluated for on element for which this object is initialized.

◆ output_sensitivity_total()

Real MAST::LevelSetPerimeter::output_sensitivity_total ( const MAST::FunctionBase & p )

◆ zero_for_analysis()

void MAST::LevelSetPerimeter::zero_for_analysis ( )

virtual

zeroes the output quantity values stored inside this object so that assembly process can begin.

This will zero out data so that it is ready for a new evaluation. Before sensitivity analysis, call the other method, since some nonlinear functionals need the forward quantities for sensitivity analysis, eg., stress output.
