Altair Inspire Fluid – Setting up a Fluid Flow Simulation

Inspire Fluids supports internal flow and thermal-related simulations.

Internal fluid flow is shown in the following steps:

Step 1: Import Geometry

In this example, a manifold is imported. It is, however, possible for geometry to be modelled directly within Inspire.

Step 2: Designate the fluid domain

Click on the Designate Fluid Domain icon, and the fluid domain is automatically selected.

Selection of the fluid domain

Right-click on the fluid domain to select and assign the material.

Step 3: Set up inlets

Click on the Inlet icon, select the inlet of the manifold, and apply the average velocity and inlet temperature.

Step 4: Set up outlets

Click on the Outlet icon and select the manifold outlets to apply outlet pressure.

Step 5: Set up solver settings

Click on the Custom Fluids Run icon.

Select the Simulation tab.

  • The appropriate settings are selected for this tutorial.
  • Click the Zone Refinement icon, then use the white arrows to adjust the refinement box to specify critical regions of the flow geometry for the analysis.

  • Click Run to start the simulation.

Step 6: View run status and plots

Click the View Convergence Plot satellite icon to view the plots from your analysis. Thus allowing you to check the convergence of the simulation.

Step 7: Post-processing

The analysis explorer shows the contours of the flow parameters, streamlines, animations, and vectors for your analysis results.
