Analysis Advisor: Guides designers and novice users step-by-step through their specific analysis problem. Helps answer common questions relating to what study type to use, what to do if mesh fails and how to interpret the results.

Analysis Library: Creates templates of commonly used analysis specifications such as loads, supports, and contact conditions. Users can simply drag and drop the templates to create loads/supports on any model.

Pin Connector: Simulates the behavior of the pin to transfer loads between two components in an assembly. It is not necessary to include the pin component in the simulation.

Spring Connector: Simulates the effect of connecting two components by a spring. It is not necessary to include the spring component in the simulation. Additionally, spring connectors can also simulate compressive/tensile preload.
Bolted Connections: Simulates the behavior of two components held together by bolts or simulate components that are bolted to the ground. Can simulate the effect of torque due to bolt tightening.
Spot Weld Connector:  Simulates spot weld connections to analyze spot welded sheet metal assemblies. Can be done in a simple one step process rather than the tedious and time consuming traditional procedure.
Elastic Support: Simulates the effect of flexible supports such as mounting pads for machinery to absorb vibrations.
Link Connector: Simulates the connection between components at two locations connected by a rigid link. The link allows components to maintain a constant distance between them while allowing relative rotation.

Virtual Wall: Defines contact between a body and a virtual wall. Can be used to simulate the behavior of walls, floors, and other flat surfaces that exist in real life.

Hinge Restraints:  Simulates a hinge restraint in a single step. Hinge restraints can be applied to cylindrical faces such as holes and shafts.

Analysis Research:  Similar to the Research option in Microsoft Word, users can now search hundreds of COSMOS Knowledge Base web-based articles without ever leaving the COSMOS interface. In addition, they can also search materials on matweb.com and access other useful resources such as COSMOS newsgroups, subscription support, downloads, and license requests.
Drop Test: Drop test helps design products that are likely to be dropped. It helps to study the effect of impact on the model when dropped from various heights. Performs drop tests onto a rigid or flexible floor.
Correlate Test Data With COSMOSDesignSTAR Results: Compares the analysis result such as stress, strain, and displacement with measured values from physical testing.
Bearing Load: Defines bearing loads that develop between contacting cylindrical faces. The bearing load automatically generate a non-uniform pressure at the interface of contact.
Non-Uniform Force and Load: Simulates variable pressure and forces.
Parametric Studies: Associates all Loads, Material and Geometric dimensions as parameters. Using design tables these parameters can be varied during a run to study various what-if scenarios. Additionally a summary listing various results for each design set is also presented.

Make Mesh Invisible

 

Mixed Meshing: Analyzes assemblies of thick and thin components efficiently by using a combination of solid mesh for thick bodies and shells for thin bodies.

Assemblies with Clearances: Most assemblies have a small clearance between the parts to account for manufacturing tolerance. Now users can bond these parts even if the assembly components do not touch each other.

Multi-body Support: Analyzes parts with multi-bodies. Users can mix different mesh types (solid and shell) and define contact conditions between the multiple bodies in their parts.

h-Adaptive Convergence: Automatically converges to correct results using h-adaptive technology. Convergence is achieved through an iterative process. In each iteration, the mesh in critical areas is automatically refined to produce correct results.

Enhanced No Penetration Surface-to-Surface Contact: A generalized “No-penetration” surface-to-surface contact can be defined between faces of assembly components in static and thermal studies. Accuracy improvement is very significant in contact analysis for assemblies with vastly different material properties.
Advanced Analysis

 

Fatigue Analysis: Performs fatigue analysis to predict the failure of structures under cyclic loading. Different S-N curves can now be defined for each component in an assembly which is integrated within the material database.

Fatigue - Load History Data: Variable amplitudes for loading events. Load history curve data for an event can be imported from a text file.

Fatigue - Rainflow Charts & Mean Stress Correction: Plots rainflow and damage matrix charts at any given location. Supports the mean stress correction option using either Soderberg or Goodman theory.

Nonlinear—Automatic pseudo time-varying conditions for Restraints and Loads: Automatically creates a pseudo time-varying condition for any prescribed Restraint or Load.

Nonlinear - Hyperelastic & Viscoelastic: Define or import engineering curve data into COSMOSWorks material database to automatically compute material constants for hyperelastic and viscoelastic materials.

Nonlinear - Nitinol: Predefined material model for Nitinol in the COSMOSWorks material database. Nitinol is a shape memory alloy used in internal medical devices such as stents.

Validation Examples: Numerous verification problems for linear and non-linear analysis to demonstrate the accuracy of results in comparison to analytical results.

Customize Default Plots: Allows you to specify which plots will be created by default after an analysis has run. For example, users can specify that all mode shape plots be created following a frequency analysis run.
Enhanced Usability

 

Edit/Create Material Libraries: Add or edit linear, nonlinear, thermal and fatigue material properties in a single step using the built-in material editor.
Shell Analysis for Assemblies:  Analyzes assemblies of sheetmetal or thin components using shell elements. Bonded, gap or contact conditions can be defined between shell surfaces of an assembly.
Analysis Quick Tips: Walks you step-by-step through the analysis process from defining a study to visualizing the results
Context sensitive menus for Load/Restraints: When defining loads or restraints in a model, context sensitive menu is available on the graphics area to make it easy to apply loads or restraints on selected faces, edges or vertices.
Enhanced eDrawings Support: Creates a single compact eDrawings file with multiple results plots. In addition, users can hide selected parts of an assembly to better visualize the results.
Easier to Specify Direction of Loads and Restraints: Allows you to select an edge or a face specify the direction of loads and restraints.
Buckling Due to Thermal Effects: Simulates buckling caused by temperature distribution.
"What's Wrong" Indicators:  Gives a visual indication of the current status of analysis results in the Feature Tree. When there is a change in the geometry, material, loads or restraints, the “What's Wrong” message box lists detailed diagnostics messages regarding the warnings and errors.
Improved toolbars and XP style icons: Includes improved Windows XP style 256 color icons. These icons are clearer and have more depth to them.

Analysis File Management: Provides more options for analysis results locations. Choose to keep the results in either the CAD model folder, a sub-folder under CAD model location, or a default results folder. Users can also define separate results file locations for each study.

Using Steady State Thermal Results as Initial Condition in a Transient Thermal Analysis: Uses a temperature profile calculated by thermal analysis as an initial condition to a transient thermal study.

Surface to Surface Radiation: Simulates radiation exchange between parts. COSMOSDesignSTAR automatically computes the view factor needed to accurately calculate the heat exchange.
Allows you create extruded or revolved geometry from the 2D-sketches.
Seamless Load Transfer From COSMOSMotion: Reads motion loads without a need for any external file thus making the process seamless. In addition, there is an option to read the loads for the entire motion cycle.
Coupled Structure-Flow Analysis: Reads pressure and temperature distribution from EFD.Lab analysis for structural analysis.
Improved Section and Iso Plots: Allows you to choose any CAD plane as the clipping plane. In addition users can move and rotate the clipping plane dynamically and see the effect on the result plots.
Improved Animation of Transient Thermal Results: Allows you to specify the starting and ending solution steps for animation. In addition the number of frames for animation has been increased to 100.
Identify Results Locations on the Model From Results Listing: identifies the result locations on the model when selecting them from the List Selected dialog box. In addition, you can now graph the variation of results like stress, displacement, etc., along an edge.
Improved Vector Plots: Allows dynamic control over the size, density and color of vectors in vector plots. Also, the principal stress vector plots now visually indicate the tensile/compressive nature of stress.
Iso Value Indicators: An arrow indicating the iso value now appears in the plot legend. In addition, Iso plots allow you to display the percentage volume of elements that have values greater than or equal to the iso plot value.
Yield Indicator: An arrow indicating the yield strength now appears in the stress legend.
Plot Contact Pressure Distribution: You can visualize the magnitude and direction of contact pressure distribution developed between components.
