Effect of Shell Shape and Formulation on Output
Effect of shell shape and formulation on output
Thin shells in Ansys LS-DYNA may be quadrilateral or triangular; they may have a single integration point on plan, or be fully integrated; they may have from 1 to <n> integration points through their thickness; they may be linear (3 or 4 noded) or parabolic (6 or 8 noded).
Regardless of any of these permutations:
| - | On plan: | If <maxint> is POSITIVE then shells only report results at their centre. For fully integrated shells this will be the averaged value of the in-plane integration points. |
| If <maxint> is NEGATIVE then shells will report results at 2 x 2 in-plane integration points. | ||
| - | In elevation: | Shells only report results at <maxint> points through their thickness. |
( <maxint> is on the *DATABASE_EXTENT_BINARY card, and is explained in Controllable contents of the complete state file )
Sounds simple? Well it isn't! There is lots of scope for misunderstanding thin shell results, and if you have doubts please read this section. If you are still confused after that please contact Oasys Ltd Support for help and advice.
