Detailed Description

Driver for assembly of unstructured 3D spline mixed FE models.

This class implements a two-field mixed formulation with splines as basis functions. The first field is of one order higher than the second field, and its basis is obtained by order-elevating the input spline object once. By default, the geometry is represented by the second (lower order) basis, however, by negating the n_f1 argument to the constructor, the first basis is used instead.

Member Function Documentation

◆ clear()

void ASMu3Dmx::clear ( bool retainGeometry )

virtual

Clears the contents of the patch, making it empty.

Parameters

[in] retainGeometry If true, the spline geometry is not cleared. This is used to reinitialize the patch after it has been refined.

Reimplemented from ASMu3D.

References ASMu3D::clear(), and m_basis.

◆ evalSolution() [1/7]

LR::LRSpline * ASMu3D::evalSolution

Projects the secondary solution field onto the primary basis.

Parameters

[in] integrand Object with problem-specific data and methods

◆ evalSolution() [2/7]

bool ASMu3D::evalSolution

Evaluates the secondary solution field at all visualization points.

Parameters

[out]	sField	Solution field
[in]	integrand	Object with problem-specific data and methods
[in]	npe	Number of visualization nodes over each knot span
[in]	project	Flag indicating result recovery method (0=none, 'D'=direct evaluation, 'S'=superconvergent recovery)

The secondary solution is derived from the primary solution, which is assumed to be stored within the integrand for current patch. If npe is null, the solution is recovered or evaluated at the Greville points and then projected onto the spline basis to obtain the control point values, which then are returned through sField. If npe is not null and project is defined, the solution is also projected onto the spline basis, and then evaluated at the npe points.

◆ evalSolution() [3/7]

bool ASMu3Dmx::evalSolution	(	Matrix &	sField,
		const IntegrandBase &	integrand,
		const RealArray *	gpar,

	)		const

virtual

Evaluates the secondary solution field at the given points.

Parameters

[out]	sField	Solution field
[in]	integrand	Object with problem-specific data and methods

The secondary solution is derived from the primary solution, which is assumed to be stored within the integrand for current patch. When regular is true, it is assumed that the parameter value array gpar forms a regular tensor-product point grid of dimension gpar[0].size() X gpar[1].size(). Otherwise, we assume that it contains the u and v parameters directly for each sampling point.

◆ refine() [4/4]

bool ASMu3D::refine

Refines the parametrization by inserting extra tensor knots.

Parameters

[in]	dir	Parameter direction to refine
[in]	xi	Relative positions of added knots in each existing knot span

◆ remapErrors()

void ASMu3Dmx::remapErrors	(	RealArray &	errors,
		const RealArray &	origErr,
		bool	elemErrors

virtual

Remaps element-wise errors from geometry mesh to refinement mesh.

Parameters

[out]	errors	The remapped errors
[in]	origErr	The element-wise errors on the geometry mesh
[in]	elemErrors	If true, map to elements and not basis functions
