Detailed Description

Module for precomputed quadrature for tensor product B-splines.

A TensorProdQuadrature object is provided wherein the values of the B-splines at the quadrature nodes are precomputed and stored

Function/Subroutine Documentation

pure subroutine, public m_tensorprod_quadrature::evaluate_at_nodes	(	type(tensorprodquadrature), intent(in)	this,
		procedure(user_function_3d_interface)	f,
		integer, intent(in)	ii,
		integer, intent(in)	jj,
		integer, intent(in)	kk,
		real(wp), dimension(1:, 1:, 1:), intent(out)	f_vals )

Evaluate the function f at the quadrature nodes on the (ii,jj,kk)-th interval.

Parameters

[in]	this	The TensorProdQuadrature object
[in]	f	The function to evaluate
[in]	ii	The index of the interval in the x direction
[in]	jj	The index of the interval in the y direction
[in]	kk	The index of the interval in the z direction
[out]	f_vals	The values of the function at the quadrature nodes, shape (n_quad_z, n_quad_y, n_quad_x)

Note: The output array f_vals is intentionally in reverse order, as this facilitates its use with the current loop-order in the mass matrix assembly
