Problem about 'ShellNLDKGQ'

[jhj]

Hi, I have a question about shell element.

I am conducting a dynamic analysis.

It's passing a vehicle load on top of the shell element.

When 'shellDKGQ element' was used, 'stress' values could be extracted through 'element recorder'.

However, when using 'shellNLDKGQ', it seems that 'stress' value for vehicle load is not extracted.

Is there another response extraction command for dynamic analysis in 'shellNLDKGQ'?

I'll be waiting for your answer.
