Before we get started with the basics of mesh sizing in the Ansys workbench, let’s explore meshing in brief.
One of the most crucial processes in carrying out an accurate simulation using FEA is meshing. A mesh is composed of elements that have nodes—coordinate positions in space that might change depending on the element type—that symbolise the geometry's shape. Uneven forms are difficult for an FEA solver to work with, but typical shapes like cubes make it much happier. Meshing is the process of transforming amorphous shapes into "elements," which are more discernible volumes. Before starting with meshing, you would need to feed the CAD model/design into a simulation software like Ansys.
As meshing is a process that demands a great deal of accuracy, it is important to work with sophisticated software like Ansys. Obtaining simulation results often take a long time, therefore, Ansys Meshing has developed sophisticated automated mesh creation systems that can offer CFD & FEA Meshing solutions that are quicker and more accurate.
The sizing can be inserted by right-clicking on the Mesh→Insert→Sizing. Whenever the user wants to improve or just change the element size for a specific model or a part of a model instead of trying to change the mesh for the whole body, Mesh sizing is used.
The Mesh Sizing can be used to set the following:
The Scoping method, the geometry selection and the suppressed definition are the same in terms of use as discussed in the earlier article in Inserting the Method.
Definition
A. Type
The type of sizing decides the way in which the elements are sized with respect to the various selection methods. The various types are discussed below.
Advanced
A) Global Defeature Size
B) 50% of the value of the local Element Size

Tetrahedral is a four- nodded solid element that can be generated through the tria element by creating a volume and also through the existing volume of the geometry. These elements are used where the geometry has high thickness and complexity. The image attached below is a representation of a Tetra element. The Tetra element will have 4 triangular faces with four nodes joining them together

A connector is a mechanism that specifies how an object (vertex, edge, or face) is connected to another object or the ground. By often simulating the desired behaviour without having to build the precise shape or specify contact circumstances, connectors make modeling simpler.
