undergraduate question: gauss points

Hi,

How can I calculate the gauss point locations for Brick, Bbar Brick, etc.? I'm happy to work within the C++ code that's there, any hints you could give would be great.

thanks for your time,

alisa

you might want to google Gauss Quadrature, it's a numerical integration method.

OK, thanks.! I think I've got it; have to do some scaling:
distance between nodes maps to length 2 (-1 to +1 ) and the gauss locations map to 1/sqrt(3) in from the nodes, right?

thanks!
