Joining 2D mesh to 3D mesh

Hello Everyone,

 

I have been trying since very long on this problem but couldn't find a proper solution. I am experimenting on simple models to see whether the load between the shell and solid is transferred correctly or not. I have considered following three cases:

  1.  A plate (100 mm * 100 mm * 8 mm) modeled completely with hex elements
  2. Same plate modeled completely with shell elements
  3. Half of the plate modeled with hex elements (from fixed end) And remaining half with shell elements

The actual problem is the 3rd case, and to verify it's results, 1st two cases are being studied. I have tried different approaches (such as with skin elements, tie contact, penetration) but the answers were not matching with the 1st two cases. [The max. von mises stress in the 1st case =5.2e-1 MPa , and max. displacement in 1st case = 1.43e-2 mm ] 

 

The plate is fixed with a cantilever support and the force is applied at the free end (shown in the attached force - time graph )

 

Anybody please get me solved the .hm file attached herewith in the radioss solver. I also want to solve and test the results using RBE2 and RBE3 elements, but I don't know how to use them at the join between 2D and 3D mesh in my case. It would be of great help if the use of RBE2 and RBE3 would be demonstrated.
