Add a Free Triangular node (

) 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 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 Smooth across removed control entities check box to smooth the transition in element size across removed control entities. You can specify the number of smoothing iterations in the
Number of iterations field. In the
Maximum element depth to process 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 Automatic (default) to let the software use the best suited method, select
Delaunay to use a method based on a Delaunay algorithm, or select
Advancing front to use a method based on an advancing front algorithm.
