Learn how to Use FloEFD in Solid Edge to Perform a Fluid Analysis

With FloEFD and Solid Edge, you now have the tools and ability to analyze computational fluid dynamics (CFD) directly in your CAD program.

In this Snackbyte video, PROLIM Application Engineer, Ben Weisenberger, demonstrates how to use FloEFD to analyze a flow and thermal management problem.

While the component you’re working on might not always be a sewing machine, there are several steps you can use from this video.

Let’s take a look at how you’ll want to set up your analysis using FloEFD in Solid Edge:

How to Run an Analysis in FloEFD

  • Start by using the Wizard tool to set up the basic definition of your analysis.
    • Name project and select a unit system.
    • Define the analysis type (internal or external).
    • Choose the specific physical features of your model (in this case, Ben chose heat conduction in solids and a fan for cooling).
    • Select the fluid types.
    • Select the type of solid you’re working with.
  • Next, resize the computational domain around the model. You can resize the area you’re working in by simply grabbing and dragging the arrows of the domain.
  • Assign any specific regions (rotation, for example) to necessary parts (the fan). You’ll be allowed to select specific values to these regions, like assigning an RPM to the fan.
  • Assign properties to any of the solid materials. In this video, Ben is defining the motor.
  • Assign any heat sources (again, in this case, the motor).
    • Then choose a solid component that fills the interior of that solid.
  • Before running your analysis, you’ll want to assign goals. Goals are important for two reasons:
    • They act as a way of extracting quantities of interest from the analysis (how hot the motor will get, for example).
    • They help guide the convergence of the run—the solver will look for these goals to reach a steady solution before the solver stage is complete.
  • When you’ve completed these steps, you’re ready to run your analysis!
