how to output the coordinates (x,y,z) of gauss points

[ouyang]

Hi everyone,
I am using the brickUP element for my 3D geomechanics problem and want to draw stress contour. To do so, I output stress for 8 gauss points (see the following "recorder Element ...". But I don't know how to get (x,y,z) coordinates of the gauss points. Anybody knows how to output (x,y,z) so I can draw the stress contour on x, y coordinates?

recorder Element $elementList -time -file stress1 -dT $dt material 1 stress
recorder Element $elementList -time -file stress2 -dT $dt material 2 stress
recorder Element $elementList -time -file stress3 -dT $dt material 3 stress
recorder Element $elementList -time -file stress4 -dT $dt material 4 stress
recorder Element $elementList -time -file stress5 -dT $dt material 5 stress
recorder Element $elementList -time -file stress6 -dT $dt material 6 stress
recorder Element $elementList -time -file stress7 -dT $dt material 7 stress
recorder Element $elementList -time -file stress8 -dT $dt material 8 stress

Thanks for your help.
