Axisymmetric analysis in ANSYS

Axisymmetric analysis is supported in the ANSYS Structural, Thermal, Axisymmetric Structural, and Axisymmetric Thermal environments.

To use axisymmetric elements in both axisymmetric or non-axisymmetric environments, you must set a value for the 2D Solid Option when you create a new FEM or Simulation.

• None (Structural and Thermal environments only) – No axisymmetric elements can be used.

• XY Plane, Y Axis – If axisymmetric elements are used, they must be on the XY plane. The axisymmetric rotational axis is Y.

The ANSYS Axisymmetric Structural environment has the following additional features, which allow you to define more complex axisymmetric parts:

• You can define concentrated masses in the axisymmetric environment. This allows you to model such things as combined masses of a blade array in turbo machinery applications.

• You can define beams, bars, rigid links, and springs. Beam sections are applied in the same way as in other ANSYS environments. The addition of 1D elements allows you to connect point masses and loads to the rest of the geometric model.
