Sequential loading with nonlinear geometry

Structural sequential analysis, where multiple structural analyses can be linked to each other, is now supported for structural non-linear geometric analysis.

You can access this function from the Analysis menu, the Analysis workbench toolbar, or by right-clicking on a supported structural analysis to create a linked analysis.

Imported virtual bushings

Virtual bushings under connections can now be imported from a .csv file. To import a virtual bushing; the bushing coordinates, linear and rotational stiffness along all the three axis, and a coordinate system are required. The bushings are mapped based on the specified diameter. It is connected to two parts that fall within the specified diameter from the input coordinates.

Contour plots in local coordinate system

All contour plots for structural and modal analysis can now be plotted along a local coordinate system. The local coordinate system can be Cartesian or cylindrical. The Set Output Coordinate System settings can be accessed from the legend. Pick info and Result graph outputs results based on the output coordinate system.

Fatigue based on structural nonlinear

Fatigue analysis can now reference structural nonlinear analysis with separating contact. This is supported in addition to structural linear analysis.

Spatial reader

A new geometry reader called Spatial reader is supported for CATIA V5 and V6 files. The reader can be picked from Settings > Geometry import settings > CAD reader.

Rigid body mode cutoff

Cutoff for rigid body modes in dynamic analysis can now be defined. The default is set to 1 Hz.

Improved solution settings

Solution settings have been re-factored to have two higher level adaptations called Global and Global + Local.

Global adaptation is best for general load path prediction, modes and/or thermal analysis.

• Uses three adaptive passes and Adapt to thin solids
• Refinement level is set to Standard
• Only uses global adaption

Global+Local is best for stress calculation with more precision.

• Uses four adaptive passes
• Adapt to features
• Adapt to thin solids
• Automatically creates local group for the parts and segregates based on its relative volume
• Can be used for both global and local adaptations
• Refinement level is set to Standard

In addition to higher level adaptations, there is a new option available under custom solution settings that automatically creates local groups for the parts and segregates them based in its relative volume.

New approach for bolt tightening

Bolt/nut tightening is now performed as active load. The target axial force is now precisely achieved.

Import remote loads with custom coordinate system

Imported remote loads from a .csv can now reference a custom coordinate system in addition to the global coordinate system.

Product editions

Product editions can now be selected from Settings > License. Product editions including Basic, Standard and Advanced are available. In addition to them, a Trial edition is also available that gives access to the Standard version for 30 days.

Re-factor material database

Material database has been re-factored such that materials can be created based on specific physics such as mechanical/thermal. Mechanical properties are not required to be input to just run thermal analysis and conversely.

Re-factor spot welds

Spot welds have been re-factored to represent 2T/3T/4T welds appropriately. All the welds are not converted into 2T welds anymore but are rather represented as created in the Project Tree.

When spot welds are imported from a .csv, the order of spot welds is also maintained.

In addition to spot weld re-factor, the number of spot welds are also captured in the Project Tree Spot Welds info.

Re-factor boundary conditions for dynamic analysis

You can now apply multiple boundary conditions to the same geometric entity for dynamic analysis. This allows applying different load functions along different directions.

Applying multiple load functions to the same boundary condition has now been disabled.

Save RMS response to project file

RMS von-Mises stresses are also now saved to the project file after evaluation.

Solving linked analysis

All linked analysis are solved automatically without using the solve manager. This applies to all linked analysis including structural, buckling, modal prestressed, dynamics, thermal stress and squeak and rattle.

Updated CAD import formats

The list of supported CAD formats are updated.
