Contact interface

Altair Forum User

Hello,

I am trying to setup a crash of a bumper geometry. The bumper consists in 1 curved beam and 2 crash boxes.

I used contact interface type 7 but I am having some errors.

 

ERROR ID :           59
** ERROR IN PROPERTY/ELEMENT DEFINITION (NUMBER)
DESCRIPTION :
   INVALID PROPERTY ID=0,
   FOR SHELL ELEMENT ID=2553

 

ERROR ID :           61
** ERROR IN MATERIAL/ELEMENT DEFINITION (NUMBER)
DESCRIPTION :
   INVALID MATERIAL ID=0
   FOR SHELL ELEMENT ID=2554

 

 ** ERROR TRAPPED : REPORT TO LISTING FILE

ERROR ID :          194
** ERROR IN HIERARCHY REFERENCE

** ERROR IN INTERFACE SURFACE DEFINITION
DESCRIPTION :
   -- INTERFACE ID : 1
   -- INTERFACE TITLE : New INTER 1
   MASTER SURFACE IS EMPTY

** WARNING IN SURFACE DEFINITION

 

Some of them refer material/proprety problems but I am sure that my material and property are well defined. 

 

 

On top of that I have this image for the parts and I don't know why. (see attachment)

Hi Tiago,

Please make sure that materials and property are assigned to the parts. Check the interface created as the error shows that the master is not selected for the interface.

Please run Model Checker (Quality>Model Checker in HyperCrash) which will list out the errors/warnings in the model.

If you still find any difficulties, please share the model.
