Target is the Designer Analyst

Designer Analyst Someone that splits time between Design and Analysis. Does not do advanced analysis. It is either not needed by the

customer or is covered by a dedicated analyst using FEMAP. Often the “super designer” at small companies being asked to

do more faster. Desires

Easy of use.

Geometry only commands.

Extended help and guidance relative to “dedicated analysis” tools such as FEMAP.

Familiar interface.

Understandable results.


Designer Products - Differences With Analysis Products

Geometry Focused – Designers will work only with Geometry (i.e. Force on face). You will need a high end product (FEMAP, NX Advanced Simulation,) to work directly with nodes and elements.

Single Solver – SE Simulation will use only NX Nastran. Femap supports multiple solvers.

Designer Language Rather than Analyst Language

Easy Geometry Modification Capability –Synchronous Technology has interesting potential for CAE model preparation.

More Process Oriented – UI organized to step you though a process. More help and suggestions to guide the designer when problems occur.


Analysis Steps

Model Preparation and Simplification– Modify “designed” geometry to meet the needs of analysis.

Preprocessing – define the loads, constraints, material properties and connections between assembly parts.

Mesh – define the type of mesh to be used and refine it as needed.

Solve – The solve occurs when the FEA model composed of the mesh, loads, and constraints are passed to NX Nastran for analysis.

Post Processing – examine the results from NX Nastran using various visualization and reporting tools.


A Quick Analysis

Demo

(At PLM World, a demo was given here)


Environment

► A new Tab and Ribbon bar in Part, Assembly, SM environments.

►integrated into these environments ►(turned on with License)► A Simulation navigator is provided for Studies►Can also be used as an alternative to the ribbon bar for

command access.


Environment Simulation Tab

Part – Analysis Tab

Assembly – Analysis Tab


Study Navigator

Provides a tree view with drag and drop functionality for working (create, edit, delete, copy, etc...) with FEA Analyses/Studies, load sets, and constraint set results

It is important to note that an analysis study can be totally defined through the Study Navigator

With a RMB click the user can define geometry, loads, constraints, mesh, etc….


Study Navigator

A Study can be created by RMB clicking on “Simulation” in the study Navigator

Once the Study is created the user can easilyrename, copy, delete, modify, solve, or usethe save to Femap .mod file

material can be added or changed


Demo

Study Creation



Mechanical Loads

► Covers the available geometry based FEMAP mechanical Loads.

► Temperature load (for body only – thermal expansion)

► Handles for defining direction, orientation.

► Quick bar options for input.


Constraints

The following types of constraints are supported Fixed Pinned No rotation Sliding Along Surface Cylindrical

Valid entities to select are faces, edges, and points (vertex)


Demo



Meshing

Support for 2D Mesh and 3D tetrahedral mesh.UI options that change between environments (i.e.

Sheet metal defaults to 2D mesh) The “Mesh” commands can be executed from

either the command bar or from the study Navigator.

command to set the mesh sizing for edges and faces.


Demo

MeshMesh Sizing



Solve Command

Command to run the analysis (execute NX Nastran)

UI to expose some NASTRAN options (GEOMCHECK)

Key piece of this will be handling NASTRAN errors in a user-friendly way.

Some UI for displaying actual NX Nastran errors for more advanced users.


Post processing – plots and graphics

Colorized plots, contoursDisplacement, animation, mode

shapes.Internal and External element

displayDisplay of results in context of

assembly, other graphics.


Color Bar

Provide additional indicators for key material properties. Provide color display options with overflow and underflow values. Saving of color bar options across sessions. Ability to position color bar at different locations and sizes on the screen.

Grayscale Rainbow Stoplight


Probe

Allow the user to probe specific node data.Creates a tool which can return information about nodes by moving the mouse

cursor over the results and their data. Provide Min-max markers for key stressProvide table with copy/paste


Reports

Create Report Similar to Femap Express HTML Output Remembers Settings!

Post ProcessingColor BarProbe



Assembly connectors

Provide the linear and glued connectors that are supported by Femap and NX Nastran.

Provide an automated tool to connect touching faces in an assembly.

Provide a manual UI for selecting faces on assemblies that will be connected.

Simulation Options

A new “Simulation” tab has been added to the “Solid Edge Options” dialog to display various Solid Edge Simulation options

Save to FEMAP

Command to create a Femap .mod file from a Solid Edge Simulation Study.

Transfers loads and constraints, mesh and results.


New “User Assistance”- combined Help and Self-paced Training

For the SE Simulation product, Education Media will implement several enhancements to the user learning experience:

• Combined user help and self-paced training-a single destination for customer learning. Single-source textual and graphic content reduces localization costs for Siemens PLM.

• Workflow-based landing pages as anchors to keep new users focused on the order of doing something and providing a link from each step directly to a procedure.

• Focused SE Simulation help file: When the user is executing a Simulation command only SE Simulation “User Assistance” is active; removes the clutter of other SE help.


Solid Edge Simulation ST3


New Loads and Constraints in SE Simulation ST3

• Adds new Torque and Bearing load to Solid Edge Simulation.

• New User defined constraint

• More options and enhancements for existing loads• Coordinate system support• XYZ component entry


Torque Load

• Great for turning shafts

• Handle for defining axis of rotation


Bearing Load

• New load for support structures

• Options for force direction and range of bearing support


User Defined Constraints

• Using this command, the user could constrain any of the six individual degrees of freedom (DOF).

• User could specify the DOF in terms of the base coordinate system or a local coordinate system.

• This command will be helpful in those scenarios where the currently supported constraints in ST2 are inadequate to define the exact constraint.

• Clickable handles show orientation and used DOF


Copy Paste and Drag-Drop for Studies

• Support Copy Paste and Drag and Drop in the Simulation Navigator.

• Study can be copied and used as base for next study.

• Loads, constraints, connectors, mesh controls can be copied into other studies.


That was just some a sampling of new functionality coming in ST3
