I modeled a cantilever with a load at its free end with a solid block at the bottom of the free end to restrict the bending. I gave fixed support for one end of the beam and the bottom surface of the Block and also i gave contact between the Block top face and the beam bottom face. Both block and the beam are not in the contact in the beginning. On running and visualizing the results the beam is bending as if there is no block it is penetrating the bloc instead of deforming.
I am performing static structural analysis
Can u suggest any corrections.

Suppress the block, assuming the block is so much stiffer than the cantilever as to be negligible.
Add a Fixed Support to the face of the cantilever beam, where the contact to the block was.

Please insert some images of your model. I can give better suggestions if you do that.

Add a frictional contact. Pick the bottom front edge of the cantilever as the Contact side of the contact and pick the top face of the block as the Target side. At the bottom of the details window is the Pinball Region. Set it to Radius and type in a number that is much bigger than the initial gap between the tip and the block.
Under Analysis Settings, turn on Large Deflection. Change Auto Time Stepping to On and set the Initial, Minimum and Maximum Steps to 100. This may be overkill, but it is more likely to get you a result. Cut it back to 10 if it works and try again.

Thanks Peter will try the same procedure as suggested by you

The procedure suggested by you is giving the similar issue , it would be helpful if you can suggest any other procedure

Please explain in detail what is going wrong in your current model and attach a copy to your reply.
