Hello Rico,

Please see if the following helps. Thanks.

Mat_117 is a resultant shell formulation and no stresses are computed. As
per the materials manual's note:

1. This material does not support specification of a material angle for each 
through-thickness integration point of a shell.

2. The objective of this resultant formulation is to provide a fast and cheap
approximation for the composite material behavior without having to to
integrate thru' the many layers of material layers. Therefore, ALL the
resultant formulated materials 116, 117, 118, 130, 139, 166, 170 are default to
1 thru' thickness integration point.
