Abaqus Standard /General contact with penetration

Submitted by chen1164 on
Dear Colleague, 
 
I am running Abaqus Examle Problems Manual 1.1.18 - The self contact on rubber gasket.  
 
I tried to convert the self contact and surface contact definition to a general contact definition. However, the rigid surface just penatrate the model like this shown below.
 
Left image is the result for the inp from manual. The right one is the result for compuation with general contact.
 
Does somebody here want to discuss or maybe explain this for me ?
 
Thank you in advance.
