Blog about stuff on Solid Edge CAD software

Solid Edge Simulation

One of the new module introduce in ST2 is the Simulation module. This extend the family of product in that field.

The simulation in the velocity series include three modules:

  • Solid Edge simulation Express (FEMAP Express)
  • Solid Edge simulation
  • FEMAP

Simulation Express is the new name for FEMAP Express. This module is dedicated to analyzing single part. The module seem to be untouched for this release. But seeing what have been implement with the new simulation i would think that new features could be transfer in it in the next couple version.

 

FEMAP is the high end application to analyze all sort of things. It is mainly compose of the NASTRAN solver to crunch the number and the layer FEMAP on top to make the bridge between the user and the solver.

 

Solid Edge Simulation

Since the introduction of FEMAP Express, Solid Edge population have request more features in that field. Solid Edge Simulation module answer the call.

The architecture of he product is similar to FEMAP, the NASTRAN core  layer with FEMAP and on top the Solid Edge Simulation interface.

One reason Siemens PLM software architect the product this way, it allow Solid Edge Simulation users to save their study to a FEMAP files to further refine the analysis. Staying in line of making sure a project can evolve inside their line of product. (scalable solution)

One of the goals of Mark Burhop the simulation product manager, was to include FEA inside Solid Edge and making sure the interface will not overflow user with too much information’s, while giving the maximum of functionalities for this first release. ST3 is in planning so if you have stuff you would like to add drop a note and i will follow them.

The new ribbon of the fluent interface was a perfect place holder for this. For old school Solid Edge user, the Fluent ribbon act like a giant V20 Ribbon bar. On the left of the screen, the vertical command panel  host sub feature.

The process inside the simulation is pretty much a linear one and it was break into seven steps.

  1. Create a new study
  2. Define geometry
  3. Define the load
  4. Define constraint
  5. Define the mesh
  6. Execute the calculation (solve)
  7. Expose/explore results and manipulate them.

Create a new study

simulation step 1

simulation step 1.1

First group in the ribbon the Study Group. From what i understand you can create has many study has you want. At this step you define the general condition of our study, the type and the mesh. Plus few more in the advance.

 

Define geometry

simulation step 2

At this step user define the solid(s) that will be part of the study.

 

Define the Load

simulation step 3

Define the load(s). Look closely at the type of load;

  • Typical force
  • Pressure
  • GRAVITY ( In the architecture this could be useful for long span)
  • Centrifugal
  • TEMPERATURE ( read metal expansion)
  • Displacement

 

Define constraint

simulation step 4 

The define constraints step allow user to define the degree of liberty the study will have.

 

Define the mesh

simulation step 6

Here you have many options to redefine the mesh according to a region, did not show but the vertical command bar list all those options.

 

Calculation

simulation step 7

The boring part of any analysis, wait for NASTRAN to do it’s job

 

Results

simulation step 8

Here user have a bunch of stuff that can be tweak to obtain the desire result.

 

This complete the first introduction tour of the simulation module of Solid Edge, hope this help you get the idea of what is coming
