Hi Karthic,

Are you using second order elements?. If so, change to first order and try running.

Please go through Example 37 - Analytical Beam in the Help Menu where thick shell formulation is used.

I have attached the model file for your reference.

Hi George,

The example you sent is working fine with thichshell.

But my case is bit different, has contact and a layer of thick shell over the solid element.

I am still getting the same error. I have attached the RAD and out file for your ref.

Please go through and correct me.

Thanks

Hi Karthic,

This error is due to the /INTER/LAGMUL/TYPE16 in the model. Please check the interfaces defined in the model.

There are many modelling errors also. Please see the image attached. I recommend you to rebuild the model.
