Dear All Experts;

I am trying to make a structural analysis.

There are reinforcements on the surface of a tank.

I modelled the tank with midsurface. But I modelled the reinforcement on the surface of tank as 3D.

when I connected the reinforcement to the tank I used bonded contact and MPC formulation.

There is gab between tank surface and 3D model. this gab is due to the thickness of the tank plate. I enclosed a photo showing this gab. I used pinball radius.

contact initial information is like that;

 

there are some forces acting to the surface of reinforcement and I am trying to find out the deformation on the tank surface.

I wonder that, this gab may affect my result?

all comments and suggestioın will be appreciated.

best regards.

Please turn on the shell thickness effect in the contact.

Dear Mr. Aniket;

thank you for your reply.

When I turn on shell thickness effect there is mark question, I think I should give a value but I do not know what it is.

could you write what I am making mistake or missing.

best regards.

What error do you see when using the show errors button?

Ok yes I solved this problem by viewing error message like you showed.

I adjusted midsurface offset type to the top, it should be middle.

when I changed offset type to the middle it is ok.

Great, just make sure the shells are where they should be by turning on Thick shells and beams and show mesh in display ribbon tab.
