CNRAGLO

0.0 < Real < 90.0
or -1.0

Default = 20.0

For CSEAM element only. Maximum angle allowed between the normal vectors of EIDSA and EIDEA or EIDSB and EIDEB. The CSEAM element will not be generated if the angle between these two normal vectors is greater than the value of CNRAGLO. This prevents generating single CSEAM element across a very curved shell configuration. See the following figure.

If α > CNRAGLO, this CSEAM element is rejected. The same check is also applied to the angle between the normal vectors of EIDSB and EIDEB.

If CNRAGLO is set to -1.0, the program will skip the checking of CNRAGLO.
