Mixed Meshing

Hello All,

I am a new user to Simulation. I am trying to study a storage rackused in a warehouse.

Initial I used beam analysis to represent the Racking, but haveheard issues with mixing mesh...and I was pointed in the directionof representing the racks as surfaces.

After creating all the surfaces (midsurfaces and adding thicknessto those parts in simulation), i cannot get the surfaces of theuprights to mesh with the cross supports. There is a gap betweenthese surfaces, so this might be an issue.

Any help would be appreciated.

Best Regards,
