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. |
Visualization of Analysis Specifications |
When you modify the design and
return to the Generative Structural Analysis workbench, the preprocessing
specifications are not automatically displayed. Workaround: Double-click the analysis specifications in the specification tree to edit the specifications. |
2D Display and Undo Command |
The creation and the edition of a
2D display does not support the Undo command. Workaround: Delete the 2D display. |
Improving Performance on Windows using the Intel Math Kernel Libraries (MKL) |
To improve performance, download the
Intel MKL library from the following Intel web site: http://developer.intel.com/software/products/index.htm To install the MKL, you just have to execute the downloaded file. Then, add the following string to your PATH environment variable:

Change in Shell Element Formulation |
The average normal vector is now used for shell elements.
where:
When the angle between the element normal and the average normal is smaller than an arbitrary value (SNORM) and if the ratio between the curvature radius and the thickness is greater than two, the average normal is used instead of the element normal for all the shell elements (TR3, TR6, QD4 and QD8). The default value of SNORM varies depending on the release.
This can slightly modify the computation results. |

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 (GPS)
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. |
Integration with Product Engineering Optimization (PEO) Product |
Do not use the local properties in the algorithm for constraints and derivative providers. |
Local Sensors: Stress Von Mises |
All the Stress Von Mises local sensors
created before the V5R15 release are invalidated while opening a .CATAnalysis
document. |
Post-processing |
Before the Version 5 Release 12:
These values are now computed according to the selected components. |
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. |
