USER WARNING MESSAGE 5276 - poor mesh

Hello Experts,

 

I have made lots of models with the following warnings:

 

...
*** USER WARNING MESSAGE 5276 (EQD8S)
ELEMENT 2055575 HAS TOO MUCH CURVATURE AND MAY YIELD POOR ANSWERS.
...
*** USER WARNING MESSAGE 5276 (ETR6S)
ELEMENT 2055107 HAS TOO MUCH CURVATURE AND MAY YIELD POOR ANSWERS.
...

 

I think it means my parabolic shell elements are "poor" meshed from NX NASTRAN point of view. But I did make element quality checks in NX Advanced simulation and didn't get any information about poor meshed elements when setting check parameters  with default values.

 

Do NX ADVANCED SIMULATION and NX NASTRAN use both different sets of element quality check parameters?

 

And by the way why do I get a second set of warnings?

 

..
*** USER WARNING MESSAGE 5276 (SQD81)
ELEMENT 2055575 HAS TOO MUCH CURVATURE AND MAY YIELD POOR ANSWERS.
...
*** USER WARNING MESSAGE 5276 (STR61)
ELEMENT 2055107 HAS TOO MUCH CURVATURE AND MAY YIELD POOR ANSWERS.
...

 

Means "E"... warnings (EQD8S, ETR6S) dealing with strains and "S"... (SQD81, STR81) means dealing with stresses or something like that?

 

If I make an element quality check in NX Advanced simulation do I have to take care of these warnings?

How can I switch it off?

 

Any suggestions will be helpful.

Best wishes, Michael
