Browsers provide a structured view of model data, which you can use to review, modify, create, and manage
the contents of a model. In addition to visualization, browsers offer features like search, filtering, and sorting,
which enhance your ability to navigate and interact with the model data.
FE geometry is topology on top of mesh, meaning CAD and mesh exist as a single entity. The purpose of FE geometry
is to add vertices, edges, surfaces, and solids on FE models which have no CAD geometry.
Tools and workflows that are dedicated to rapidly creating new parts for specific use cases, or amending existing
parts. The current capabilities are focused on stiffening parts.
Rattle evaluation is based on the assessment of relative displacement between two parts along the defined E-Line. The relative displacement is compared to the gap and tolerance values defined during the pre-processing workflow.
SnRD solution analyzes squeak and rattles for static and dynamic load types. In the post-processing module, a combined
loading module is available to study combination scenarios.
Once risk and issue areas are identified and their root cause (mode shapes and frequency), you can setup an optimization
solver deck to get solution proposals. Problems are categorized as systematic issues and non-systematic issues.
Use PhysicsAI to build fast predictive models from CAE data. PhysicsAI can be trained on data with any physics or
remeshing and without design variables.
Explore, organize and manage your personal data, collaborate in teams, and connect to other data sources, such as
corporate PLM systems to access CAD data or publish simulation data.
SnRD Post-Processing proposes two modules: Modal
Contribution and Modal Sensitivity.
Modal Contribution
The E-Line method is a time domain analysis approach, using Modal
Transient Analysis, also known as the Modal Superposition Method. This enables a
transition to the frequency domain.

Where:
is the time domain displacement.
is the number of modes extracted.
is the Modal displacement
for a mode .
is the Participation
factor for mode .
With all the above responses available in the standard outputs from OptiStruct Analysis, the Relative Modal Contribution [%]
values can be calculated. These will describe the participation of a mode or modes
on a peak of the time domain response.
Modal Sensitivity
Use modal sensitivity to live perform what-if studies by altering the time domain
response of an E-Point or complete E-Line. This is achieved by
decomposition of the Modal Superposition response, applying a factor (between 0 and
1) on selected modes, damping, and canceling or isolating them.
