Create a 2D free mesh

1. Click 2D Mesh .

2. Select the midsurfaces or faces to mesh.Note: You can use the Method list on the Top Border bar to select the faces. For more information on the available selection methods, see Selection methods.

3. From the Type list, select the type of element to generate. The available types depend upon your specified solver and analysis type.

4. From the Meshing Method list, select the meshing algorithm to use to generate the mesh. See Understanding the 2D meshing methods for more information.

5. In the Element Size box, enter a size, or click to have the software calculate an element size. See Understanding the Automatic Element Size calculation for more information.Note: The element size calculated by Auto Element Size is an estimate based upon certain characteristics of the currently selected geometry. You should always carefully evaluate your model and use good engineering judgment when determining the element size, regardless of whether you accept the software’s estimate or specify a different size. This evaluation should consider both the unique features of your model's geometry and the requirements of your analysis.

6. Use the options in the Mesh Quality Options, Mesh Settings, and Model Cleanup Options groups to specify additional parameters for the mesh.Note: If you are creating a 2D mesh simply to serve as a seed mesh for a tetrahedral mesh, clear the Export Mesh to Solver check box in the Mesh Settings group.

7. Specify the destination mesh collector:Select Automatic Creation to have the software create a new destination mesh collector. This mesh collector uses the default physical properties and inherits the material properties of the selected geometry.Note: If you did not use a midsurface to generate the 2D mesh, you must edit the mesh collector to specify a physical property table that includes thickness properties.To use an existing mesh collector, clear the Automatic Mode check box and select a collector from the Mesh Collector list.To create a new destination collector, clear the Automatic Mode check box and click New Collector .

8. Click Preview to view the distribution of nodes along the boundaries of the selected faces. If you are not satisfied with nodal distribution, you can modify the specified Element Size.

9. Click OK or Apply to generate the mesh.
