hi all,

 

I came across an error during the acoustic analysis. the problem seemes to be in FREEZ contact between the solid faces of the acoustic medium and shell faces of the structure. the contact is as such

 

 *** ERROR # 1904 ***
 SURFACE 13 refers to element 136350 of incorrect type.

 

If I turn off the contact the simulation works fine

SSID are solid surfaces of the solid part and MMID are the shell surface of the shell parts.

 

thanks for help in advanced.

 

Regards,

 

Uroš

    Hi @uros

     

    The issue is coming from a different element type. This is what I can make out from error message.

     

    Please look for element with ID 136350 and check if that is a compatible element.

    Is it possible to make shell to solid contact? if not that might be a problem....

     

    Do you have any idea?

    Hello,

    I encountered the same problem. for the master and slave elements of the contact they must be quad type? the type of element indicated in the error message is triangle
