Mesh Import

You can import either an Ideas (.unv) or a Nastran (.nas and .dat) mesh, and run a simulation in Autodesk® CFD. To ensure that contacting parts are differentiated from one another, assign unique material IDs when you create the mesh.

To import a mesh:

1. From the Get Started tab, click New.
2. On the New Design Study dialog, click Browse, and navigate to the working directory.
3. Select CAD Mesh Files (*.unv, *.nas, *.dat) from the file type menu.
4. Select either the unv, nas, or dat file.
5. Enter a design study name on the New Design Study dialog, and click Create new design study.

The model opens in Autodesk® CFD.

In Autodesk® CFD, set up of the scenario with materials, boundary conditions, etc.
