recorders for quad elements

[endryus]

Running an analysis with quad elements and writing results with
recorder Element -file quadstress.out -time -region 3 force
I get 2 values for each integration point.
I think the values should be three (sig x, sig y, tau xy).
Using the print element command in fact I obtain 3 values.
How can this difference be explained?

when you ask for forces you are gettting the nodal forces .. of which
there are two .. to get at the stresses use:

recorder Element -file quadstress.out -time -region 3 material 1 stresses

so to get all 12 you will need 4 files; 1 for each gauss point.

i will have a new version out by the start of next week that you
will be able to ask the stresses from the element and you will get
all 3 for each of the 4 gauss points.
