Description

CNRAGLI

90.0 < Real < 180.0
or -1.0

Default = 160.0

For CSEAM element only. Minimum angle allowed between the free edges (no other element shares these edges) of shell elements EIDSA and EIDEA or EIDSB and EIDEB. The CSEAM element will be rejected if this minimum angle is violated. See the following figure.

If α < CNRAGLI, this CSEAM element is rejected (for clarity suppose that the bold lines are the only couple of free edges, while the others are connected with shell elements not shown in this figure).

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