Bending Stress and Load Application on layer - Solid Mechanics

Hi,

I am trying to apply an uniformly distributed load on the Module Top surface with extreme ends of Module fixed to find Bending Stress, But I find only Point Load/ Edge Load / Body Load , not on the Layer.

1. Is it possible to select a layer on top and apply the load (Layer load).

2. Calculation of Bending Stress is not available, only available are - Normal / Shear / Mises Stress , etc.. How could I find and plot the Bending stress of my module ?

   Kindly share your ideas.

   Thanks.
