# All The Nodal Boundary Conditions In ANSYS® Mechanical

Nodal boundary conditions are very important in ANSYS® analyses to define them by selecting proper nodes. First of all, we need to create our mesh structure. Because nodes are the elements of mesh structures.

So, you can define boundary conditions by selecting nodes, which will make your boundary conditions of the simulation or analysis will be more compliant with a mesh structure.

There are various kinds of boundary conditions available in ANSYS®. And also, you can define some of them as the nodal basis. Here, we will show you which boundary conditions that you can define as a nodal basis in ANSYS.

## Node-Based Boundary Conditions In ANSYS®

• Nodal Force In ANSYS®: In physical models, forces are a very important aspect. Defining forces as boundary conditions is very important for engineering analyses. In ANSYS®, you can define node-based forces by selecting nodes from the mesh structure of the simulation model.
• Nodal Pressure In ANSYS®: Pressure is the force application into the unit area. So, the logic of pressure is nearly the same as the nodal force. You can see the detailed information by clicking the given links.
• Nodal Displacement In ANSYS®: You can also define displacements as node-based which is very important to see the stress and strain distribution on the model at the defined displacement in ANSYS®.

Node-based boundary conditions are also used in academic studies about finite element methods. Comparisons can be made between a finite element model of basic physical systems. You can create these theoretical models in ANSYS® with these nodal boundary conditions.
