Why i am not able to change the Symmetric Axis

[rajesh.parameshwariah]

For some reason i am not able to change the symmetry axis for my 2D axisymmetric analysis. The system is rotating my model at Y axis instead of X axis... i have been trying to change it in the symmetry option but it is not taking it. see the attached pics..

Hi

In a 2D axisymmetric analysis within Workbench Mechanical Static Structural Analysis, the model must be positioned with the Y-axis as the axis of symmetry. This configuration is essential for accurate analysis. The X coordinates denote the radial direction, while the Y-axis consistently serves as the axis of symmetry. Additionally, it’s crucial to set the analysis type to 2D when selecting the geometry cell. =>

So that means of course that you can not use a symmetry region object in a 2D axisymmetric analysis (as you saw it is not allowed – just follow the guide and procress described above.

Just rotate your parts in SC DM or Discovery so that the Y-axis is the axis of symmetry
