21 January 2020 11:07:20 AM TRIANGLE_EXACTNESS C version Investigate the polynomial exactness of a quadrature rule for the triangle by integrating all monomials of a given degree. The rule will be adjusted to the unit triangle. TRIANGLE_EXACTNESS: Enter the "root" name of the quadrature files. TRIANGLE_EXACTNESS: Please enter the maximum total degree to check. TRIANGLE_EXACTNESS: User input: Quadrature rule X file = 'strang5_x.txt' Quadrature rule W file = 'strang5_w.txt' Quadrature rule R file = 'strang5_r.txt' Maximum total degree to check = 5 Spatial dimension = 2 Number of points = 6 Error Degree Exponents 9.99201e-16 0 0 0 6.66134e-16 1 1 0 6.66134e-16 1 0 1 2.22045e-16 2 2 0 8.88178e-16 2 1 1 2.22045e-16 2 0 2 1.11022e-15 3 3 0 2.22045e-16 3 2 1 2.22045e-16 3 1 2 1.11022e-15 3 0 3 1.9984e-15 4 4 0 8.88178e-16 4 3 1 4.44089e-16 4 2 2 8.88178e-16 4 1 3 1.9984e-15 4 0 4 0.00527393 5 5 0 0.0131848 5 4 1 0.00527393 5 3 2 0.00527393 5 2 3 0.0131848 5 1 4 0.00527393 5 0 5 TRIANGLE_EXACTNESS: Normal end of execution. 21 January 2020 11:07:20 AM
