Pressure

Pressure is defined as force per unit area. The standard unit for pressure is Pascal, which is equal to 1 Newton per square meter.
Pressure = Force / Area  =  F/A

It is generally applied perpendicular to the applied surface.

In ANSYS, Pressure load applies a constant pressure or a varying pressure in a single direction (x, y or z) to one or more flat or curved surface.
A positive value of pressure act toward the face, compressing the body. A negative value of pressure act opposite to the face, form tension in body.

Analysis Type – This boundary condition are available in only following ANSYS Analysis type

  • Static Structural
  • Transient Structural
  • Harmonic Response
  • Explicit Dynamics

Properties of Boundary Condition

Dimensional Analysis

  • 3D Simulation: Supported
  • 2D Simulation: Supported

Geometry Type

  • Solid: Supported
  • Surface/Shell: Supported

Topology

  • Body: Not Supported
  • Face: Supported – 3D
  • Edge: Supported – 2D
  • Vertex: Not Supported
  • Node: Not Supported

If you select multiple face or edge, when defining the pressure, the same pressure value gets applied to all selected face or edge.
