Non-axisymmetric force applied to axisymmetric model

[Davidk401]

I currently have an axisymmetric model created, and would like to apply non-normal body force to the model from a 45 degree angle at one direction. This body would ideally be an elliptical shell. Is this possible?
I experience errors when trying to add a 3D shell to this axisymmetric assembly for obvious reasons. If this is not possible would there be some sort of simple work around solution?
Thanks in advance

Abaqus offers special elements for that - SAXA elements (SAXA1N and SAXA2N). Check the documentation chapters "Choosing the element's dimensionality" and "Axisymmetric shell elements with nonlinear, asymmetric deformation" for more details.

Thank you for your reply. Does this enable forces to be applied by another body? Or does this just make non-axisymmetric deformation possible?

Contact between parts can be included when using these elements but you have to model it with contact elements ISL or IRS. This topic is discussed in another chapter of the documentation: "Contact modeling if asymmetric-axisymmetric elements are present".

Hi, this chapter doesn't seem to address how to combine axisymmetric and asymmetric parts. I don't find it clear how to specify the angle of the circumferential plane theta.
