GASKET simulation

Hi,

I am performing an analysis using gasket materials. However, I am encountering the following error:

 

 *** ERROR # 4704 ***
 The loading path must start from the origin.
 MGASK #15 (BEHAV = 1).
 
 *** Run terminated because of error(s) in the input data.

All the loading and unloading curves start with zero pressure and at zero clearance as shown the pics.

 

Unfortunately, I am not allowed to share the model. Could someone identify the cause of this problem?

 

Thanks in advance.
