Free Triangular

) to create an unstructured triangular mesh on boundaries in 3D and domains in 2D. You can control the number, size, and distribution of elements by using Size and Distribution nodes.

To create an unstructured triangular mesh:

•

From the contextual toolbar (macOS and Linux), choose from the menu (

) (3D components) or click for 2D components.

•

Right-click a node and choose . For 3D components, this is selected from the menu.

Then enter the properties for the triangular meshing operation using the following sections:

Define the boundaries (3D) or domains (2D) where you want to create an unstructured triangular mesh. Choose the level of the geometry from the list:

•

Choose (3D) or (2D) to specify the geometric entities for which you want to create an unstructured triangular mesh. Choose in the list to select the boundaries or domains in the window or choose (3D) or (2D) to select all boundaries or all domains.

To scale the geometry during the meshing operation, change the x-scale, y-scale, and z-scale in 3D to positive real numbers. If any of the scale factors are not equal to one (1), the software scales the geometry in the x, y, and z directions before meshing. After meshing, it restores the geometry and mesh to fit the original size. The scale factors make it possible to generate meshes that are anisotropic, and they are useful if the mesh generator creates many elements due to a thin geometry or if the mesh generation fails due to large aspect ratios in the geometry.

Select the check box to smooth the transition in element size across removed control entities. You can specify the number of smoothing iterations in the field. In the field you can specify the maximum element depth, from the boundary layer interface, for the mesh points to be smoothed.

Here you can specify the triangulation method used when creating the triangular mesh. Select (default) to let the software use the method that is best suited for the geometry, select to use a method based on a Delaunay algorithm, or select to use a method based on an advancing front algorithm.
