ANSYS Structural Concepts: Boundary Conditions

This chapter reviews the general concepts of structural simulations in ANSYS, with a focus on Boundary Conditions.

Boundary conditions are used to specify how the solid domain is constrained against displacement, or how it is free to undergo displacement or deformation.

Different boundary conditions for structural simulations are defined in three main categories, including: Loads, Supports, and Inertials.

Different types of load boundary conditions:

• Pressure

• Hydrostatic Pressure

• Fluid Penetration Pressure

• Force

• Remote Force

• Bearing Load

• Bolt Pretension

• Moment

• Line Pressure

• Thermal Condition

• Joint Load

Different types of support boundary conditions:

• Fixed Support

• Displacement

• Remote Displacement

• Frictionless Support

• Compression-only Support

• Cylindrical Support

• Elastic Support

Different types of inertial boundary conditions:

• Acceleration

• Standard Earth Gravity

• Rotational Velocity

• Rotational Acceleration
