Hyperworks and nCode

Hy  every body

I have a system with differnt components. alla the components are connencted each others with the connection TIE.

I need to perform a fatigue calculation with nCode, using the gliph for vibration exciter. I computed the FRF of my model with Hyperworks then i upload the .h3d file on Ncode to obtain the fatigue damage. 

During the calculation in nCode, the software have a failed in a specific element. This element is part of the set i used for the TIE connection. 

i dont know what's wrong with the simulation. Could the TIE connection be not suitable for nCode? 

i share with you the HW model and nCode model

thank you in advance
