In the model, how to resolve the error 'Error Norm is NaN or Infinite' after creating the model using PSC Wizard?

Assuming that the deck is simply supported, the elastic link are used to emulate bearing. 

To avoid additional stresses in transverse and longitudinal direction of girder due to geometry constraint, we need to release bearing in local y and z of bearing as shown in figure.

In the model, all elastic links are having very less stiffness in local y and z direction (elastic link), thus making structure unstable in transverse and longitudinal direction and error message is displayed. This is can be updated as shown below. Similarly, elastic link are updated for all the spans.
