An error comes like 'Element (element number) has a radius/thickness ratio of (some no.). This violates assemption of shell element.' I tried changing the mesh but still same error pops up and the solution stops.

Can anyone guide how to get this error removed/resolved ? 

Thanks in advance

Hi,

Please try using a different mesh size.

Also, please see if the following link helps: 

Why does Mechanical APDL give the error, " Element xxxx has a radius/thickness ratio of xxxxxx. This violates assumption of shell element" even after turning off shape checking SHPP, OFF? - Ansys Knowledge

Tried using different mesh size but still the same error.

To expand on what Gary and Ashish have said:

The issue is happening due to the Warping of the shell elements and coming due to inadequately defined mesh, there are multiple ways to overcome this

 

1. Use linear mesh
2. Refine the mesh in the region where reported warping is high
3. Use a SOLVE,,,,,NOCHECK command to ignore the error (last resort)

Hi Deepesh

 Try adjusting the Thickness in the Surface body details. 
 Also, can you show an image of your model?
