Meshing is the most important part of Finite Elements Methods(FEM). It must be adjusted accurately according to your application type such as fluids, solids, mechanics explicit, etc. Also, meshing must be adjusted according to your computational power. So meshing has lots of parameters to optimize. So ANSYS® meshing provides various kinds of tools and options to optimize your mesh structure according to your parameters. One of these optimization options in ANSYS® Meshing is the ‘Element Midside Node’ option.

In this article we will explain;
- What is the ‘Element Midside Node’ option in ANSYS® Meshing,
- How to adjust this option in ANSYS® Meshing,
- Explanations of the ‘Element Midside Nodes’ options.
Element Midside Nodes Options In ANSYS® Meshing
The default option for the Element Midside Nodes option is ‘Program Controlled’ which means the program will select the required option according to your system or application.
Element Midside Nodes means that; You know those mesh elements constitute nodes between them and the nodes number gives the Degrees Of Freedom to the physical model. The node number inside a model changes again with the element shape and element number. But also you can increase the number of nodes in meshing elements without increasing the mesh element number with midside nodes. With the ‘Element Midside Nodes’ option, you can add a midside node to your meshing structure to increase the node number.
Kept: This option of ‘Element Midside Nodes’ keeps the midside nodes which means your node number will be increased with midside nodes.
Dropped: This option of ‘Element Midside Nodes’ deletes the midside nodes from the mesh structure. So decreasing nodes number means that the Degrees of Freedom of the model is decreased.
So this is the very straightforward explanation of the Element Midside Nodes option in ANSYS® Mechanical.
