Good afternoon,

 

I would like to know again how to defined contact between two shells that are apart by there solid thickness,

It should respect the thickness during the contact.

Shells have T thickness defined.

 

One shell group is 30mm thick and the other is 25mm thick.

The 2 contact pairs are 27.5mm apart.

Where do I add the information in the cards again to tell the contact group the correct thickness of the shells.

Regards, Harry

    Hello,

     

    Maybe your gap is to big, since there is a build in distance for gap detection (default = twice the average edge length on the master surface).

     

    Please try to set the parameter SRCHDIS in CONTACT card a little bit larger then your real gap distance.

     

    SRCHDIS:

    Search distance criterion for creating contact condition.  When specified, only slave nodes that are within SRCHDIS distance from master surface will have contact condition checked.

    Default = twice the average edge length on the master surface. For FREEZE contact, half the average edge length. (Real > 0 or blank)

     

    Regards,

    Mario
