New Features

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.
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.
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.
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.


Updated Teamcenter version
Teamcenter versions 10.0 to 13.4 are now supported.
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.
Rotations output to PUNCH file
Rotations are now output to PUNCH file for frequency response analysis.
Rigid body mode cutoff
Cutoff for rigid body modes in dynamic analysis can now be defined. The default is set to 1 Hz.

Known Issues
The following known issues will be addressed in a future release as we continuously improve performance of the software.
- Issues with linear guide joint under virtual connectors.

Resolved Issues
- For dynamic analysis, the entire available modal space is always used instead of just the modes from the frequency span.
- Issues with thermal solution when the boundary conditions are applied to a circular spot.
- Replaced Master and Mate with Primary and Secondary respectively.
- Uniform function in dynamic analysis is now defined across all the frequencies and not limited to 10,000 Hz.
- Issues with SimSolid Plug-in for Fusion.
- Imported temperatures from .csv now use geometry units for the coordinates.
- Issues with approximating imported temperatures.
- Issues with sequential analysis with alignment or inertial loads.
- Replacing a material in the Project Tree with the same material in the material database is now allowed.
