Hello,

I wounder where I can see how many integration points (in plane) in each layer of layers when I use SHELL181 elements with the Multilayer Definition. From what I can understand in the Element guide:
"The default number of integration points for each layer is three; however, when a single layer is defined and plasticity is present, the number of integration points is changed to a minimum of five during solution. " However, this is for the " through the thickness of each layer ". I want to know how many integration points are used in plane. If I use SHELL181 with full integration will there be four integration points in plane for each layer?

This is an element output quantity for shell181 as shown in table 181.1 in the element reference for shell181:

The footnote 5 says you need to use OUTRES,LOCI,ALL

Then you can use "General Postproc > List Results > Element Solution > Geometry > Element integration point." I did this for one shell181 element 1 mm square with corner at origin in XZ plane:

Or use PRESOL,LOCI.

Potting these:

These were a fraction of 0.21132 along the side length, but this was for a square element.

I tried with a 1x2mm element and the fraction from the end (0.211325) is unchanged.

Thanks alot!
