Hi there!

I am modeling a 3D beam resting on an elastic foundation in Abaqus. I would like to assign nonlinearity to the elastic foundation, but I do not know how to proceed. I know that the case for linear elastic foundation can be done in the Interaction module but do not know how to proceed for a nonlinear case. Please, I would like some directions on how to input a nonlinear elastic foundation to a 3D beam in Abaqus. Thank you for your help.

Regards,

Hley
