bool ASMs3DLag::evalSolution

Evaluates the secondary solution field at all visualization points.

Parameters

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

The number of visualization points is the same as the order of the Lagrange elements by default.

virtual

Evaluates the secondary solution field at all visualization points.

Parameters

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

The number of visualization points is the same as the order of the Lagrange elements by default.

Reimplemented from ASMs3DLag.

References MxFiniteElement::basis(), Lagrange::computeBasis(), ASMmxBase::elem_size, elem_sizes, utl::matrixBase< T >::empty(), ItgPoint::eta, IntegrandBase::evalSol(), utl::matrix< T >::fillColumn(), ASMs3DLag::getElementCoordinates(), ASMmxBase::itgBasis, MxFiniteElement::Jacobian(), ASMbase::MNPC, ASMmxBase::nb, ASMbase::nel, nxx, ASMs3DLag::p1, ASMs3DLag::p2, ASMs3DLag::p3, utl::matrix< T >::resize(), utl::vector< T >::size(), ItgPoint::xi, and ItgPoint::zeta.

evalSolution() [4/12]

bool ASMs3D::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() [5/12]

Evaluates the secondary solution field at the given points.

Parameters

[out]	sField	Solution field
[in]	integrand	Object with problem-specific data and methods
[in]	gpar	Parameter values of the result sampling points
[in]	regular	Flag indicating how the sampling points are defined

We assume that the parameter value array gpar contains the u v and w parameters directly for each sampling point. If gpar is null or empty and regular is true, the solution is instead evaluated at all element centers.

Otherwise, we assume that it contains the u, v and w parameters directly for each sampling point.
