Can I use linear materials for non-linear static simulation?

[Anonymous]

I am on a non-linear simulation for my design. Is it possible to run some portion of materials that are linear, such as acrylic, and one component is non-linear (rubber)? I got the following message and my simulation can't be solved...

Warning: One or more of the physical materials do not contain nonlinear properties. The material may not behave as expected in the current analysis type. Nonlinear properties are recommended.

Yes. You can use a linear material in a nonlinear analysis.
