Hi all, 

 

I'm facing a problem I can't fix. 

When I want to perform my dynamic analysis, I get 8769 errors like below :

 

ERROR ID: 197

REFERENCE DIRECTION IS ALMOST NORMAL TO SHELL ID=54115

 

Could you please help me to fix it ? 

For confidential issues, I can't illustrate my model...

 

Best regards, 

Raphael

    Hi Raphael,

    Do you have /PROP/TYPE9 (Orthotropic Shell Property) in your model?.

    If so, edit (Right click on Blank property and select card edit)  the blank property /PROP/SH_ORTH card and specify dummy values for Vx, Vy and Vz as shown below and try running the same.

    Hi Georges, 

     

    No I only have a P17_STACK property in my model. I've got 8 plies, 1 associated laminate then a stack property.

     

    I tried running with those values assigned to the reference vector, but I still not working.

     

    Do you have any other idea ?

    Hi Raphael,

    If possible please share the model file through the secure dropbox so that we can review and help you to sort out the issue, which will be the best option.

    Else share the starter out file.

    when assigning material orientation, make sure the direction is not perpendicular to shell elements, whose IDs are reported with the error.
