Since some messages were suppressed in the solution output file, I redirected myself to the .err file and found this error there, maybe the warnings limit within ANSYS has changed after the APDL command I input, but it is not working because of this error:nThere are two elements side by side which corresponds to the two errors I received in my output file. Can anyone guide me on how does the ansys decide on the limit of the radius/thickness ratio of an element, that below or above which it will return an error?n
