zerolengthcontact 3Delements convergence problem

[Kamesh9]

Hi all

I am trying to use zero length contact 3D elements in my bridge model between the deck and the bent cap. I want to analyze the bride for earthquake ground motions, the problem is that transient analysis is not converging. I have tried using different integrators and algorithms still i have convergence issues. Any suggestions on what should i do ?

Thanks
