Associativity Part Features vs. CATAnalysis Document |
If you delete the last feature in the specification tree of
a part linked to the analysis document, the analysis
specifications may be lost. You must re-define the design
specifications to be applied to each analysis feature
specification. Recommended methodology: Create a dummy feature to be the last feature in the specification tree, and insert all new design features before the dummy feature. |

Replacing a .CATPart in a .CATAnalysis Document |
It is strongly recommended to use publications to replace a
.CATPart by another one in a .CATAnalysis document.
Body-typed supports: if you work with the body created by default in the part document, you can replace a part by another one without using publications. |
Change in Shell Element Formulation |
The shell element formulation uses a shell normal tolerance
that varies depending on the release:
This can slightly modify the computation results. To learn more, see Generative Structural Analysis User's Guide: Frequently Asked Questions: Solver Computation: How are shell elements computed. This value can be modified using an environment variable, see Generative Structural Analysis User's Guide: Frequently Asked Questions: Singularity Computation: How to tune the singularity detection. |

1D Property: Beam from Surface Option |
Although the Beam from surface option belongs to the ELFINI
Structural Analysis (EST) product, this option is available
with the Generative Part Structural Analysis (GP1) product. The choice of this option will not be taken into account by the solver if the ELFINI Structural Analysis (EST) product is not installed. You must install the ELFINI Structural Analysis (EST) product for the Beam from surface option to be taken into account by the solver. |
Properties and Transformed Mesh Parts |
When applying a property to mesh part that has been
transformed (by transformation), the transformed mesh part
inherits this property. The transfer of the properties between the parent mesh part and the transformed mesh part with multi-selection of supports may not have the desired behavior. Workaround: create several transformed mesh parts with mono-selection of support. |
Integration with Product Engineering Optimization (PEO) Product | Do not use the local properties in the algorithm for constraints and derivative providers. |
Smoothing Post-treatment for 2D Properties |
The smoothing process (element to node) has been modified
for the 2D properties (Shell, Membrane, Shear Panel).
Previously the axis of the first found connected element was
arbitrarily chosen. The axis system at node is now the mean
axis system of the adjacent elements for characteristics
owning a local axis system. This will change results when
large angle is detected between elements connected to a node. |
