    Elements of component 1 and component 2 are not connected.Please ensure connectivity and then, have design and nondesign region for optimization.

    Still there is no connectivity in the model.Do you have access for Altair SolidThiking Inspire? Setup for analysis and optimization can be easily done in Inspire.
