Flow simulation process overview


Use this general process to define a fluid flow analysis on your assembly.

Define a flow analysis project.

Similar to QY CAD Simulation finite element analysis, use the Simcenter FLOEFD for QY CAD analysis interface to:

  1. Open your assembly model in QY CAD.

  2. Display the commands on the Flow Analysis tab and on the FloEFD Analysis pane in PathFinder:

  3. Use the Tools group→Check Geometry command to validate model geometry and verify the fluid volume of the existing model is non-zero.

  4. Use the Wizard command to define a project, including the type of analysis (internal or external), fluid substance properties, and units.

  5. Specify inputs for the calculation, including boundary conditions that mimic the movement of the fluid.

    Use the commands on the Insert group→Conditions menu to create flow inlet and outlet boundary conditions, simulate flow devices (fans, heat sinks, LEDs, plates, batteries), and specify wall conditions on selected fluid-contacting faces for both internal and external flow analysis. You also can define thermal wall conditions on external walls for internal flow analysis of heat conduction in solids.

  6. Run the solution and monitor and control the calculation.

  7. Review the graphs and plots obtained in the results.

Tip:

You can apply the fluid pressure and temperature results as inputs to a finite element analysis of your design. For more information, see Use fluid flow results in a linear static or thermal study.
