Template for the cubature rules used by Intrepid. Cubature template consists of cubature points and cubature weights. Intrepid provides a collection of cubature templates for most standard cell topologies. The templates are defined in reference coordinates using a standard reference cell for each canonical cell type. Cubature points are always specified by a triple of (X,Y,Z) coordinates even if the cell dimension is less than 3. The unused dimensions should be padded by zeroes. More...

Template for the cubature rules used by Intrepid. Cubature template consists of cubature points and cubature weights. Intrepid provides a collection of cubature templates for most standard cell topologies. The templates are defined in reference coordinates using a standard reference cell for each canonical cell type. Cubature points are always specified by a triple of (X,Y,Z) coordinates even if the cell dimension is less than 3. The unused dimensions should be padded by zeroes.

For example, a set of Gauss rules on [-1,1] looks as the following array of CubatureTemplate structs:

cubature_rule[4] = { // Collection of Gauss rules on [-1,1] { 1, ----> number of points in the rule {{0.0,0.0,0.0}}, ----> X,Y,Z coordinates of the cubature points {0.5} ----> the cubature weight }, { 2, {{-sqrt(1.0/3.0),0.0,0.0}, {+sqrt(1.0/3.0),0.0,0.0}}, {1.0,1.0} }, { 3, {{-sqrt(3.0/5.0),0.0,0.0}, {0.0,0.0,0.0}, {+sqrt(3.0/5.0),0.0,0.0}}, {5.0/9.0, 8.0/9.0,5.0/9.0} }, { 4, {{-sqrt((3.0+4.0*sqrt(0.3))/7.0),0.0,0.0}, {-sqrt((3.0-4.0*sqrt(0.3))/7.0),0.0,0.0}, {+sqrt((3.0-4.0*sqrt(0.3))/7.0),0.0,0.0}, {+sqrt((3.0+4.0*sqrt(0.3))/7.0),0.0,0.0}}, // {0.5-sqrt(10.0/3.0)/12.0, 0.5+sqrt(10.0/3.0)/12.0, 0.5+sqrt(10.0/3.0)/12.0, 0.5-sqrt(10.0/3.0)/12.0} } }; // end Gauss
