As we stated in the various article in Mechanical Base about ANSYS® Meshing, the shape of your geometry defines the general options and optimizations of the mesh structure. So the shape of the geometry used in Finite Element Methods(FEM) defines the mesh structure. ANSYS® also has very useful tools to define the mesh structure according to your geometric shape. One of them is the Proximity Size Function option in ANSYS® Meshing. In this article we will show;
The default option for Size Function in ANSYS® Meshing is ‘Adaptive’. In this option, the system defines the Size Function values according to your geometric shape and the default values of the selected Size Function are used in ANSYS® Meshing.
Proximity Size Function gives the advantage of defining the minimum element layers in the geometric features that includes ‘gaps’. So if there is an internal volumetric gap or area between two opposing faces, you can define the number of layers of mesh elements in these faces for accuracy.
You need to define the below properties for Proximity Size Function;
So the whole Proximity Size Function calculations will be performed according to these parameters that you entered in ANSYS® meshing.
