Hello,

i simulate one body that i´ve simulated before but changing some parametres and these messages are shown;

 

*** ERROR ***                           CP =      16.359   TIME= 13:32:49
 The value of UX at node 64430 is 3.328084258E+13.  It is greater than  
 the current limit of 1000000 (which can be reset on the NCNV command). 
  This generally indicates rigid body motion as a result of an          
 unconstrained model.  Verify that your model is properly constrained.  

 *** ERROR ***                           CP =      16.359   TIME= 13:32:49
 *** MESSAGE CONTINUATION ---- DIAGNOSTIC INFORMATION ***               
 If one or more parts of the model are held together only by contact    
 verify that the contact surfaces are closed.  You can use the CNCHECK  
 command to check the initial contact status in the SOLUTION module.

 

 

i dont know if they are related to de conections.

Hey,
The error suggests that there is some rigid body motion is present in the model. It happens due to under constrained model or contacts.
