While this is a simple question, I'm totally lost. Is there any general formula for generation of n-point gaussian quadrature over a triangle?
I'll use this formula to generate a variable-point (7, 10, 13, ...) gaussian quadrature tables for triangle and use it to take integrals of many triangles. In my case, simulation results are not precise enough when integrals taken with 7 point tables.
If any direct answer is unlikely, any nudge in the right direction is also very welcome.
Thanks in advance.
