Mesh Import

You can import either an Ideas (.unv) or a Nastran (.nas and .dat) mesh, and run a simulation in Autodesk Simulation 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 Simulation CFD.

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

Note: The Mesh task dialog is not available because the mesh is already generated.

Note: Mesh Enhancement does not occur on an imported mesh.
