Abaqus error/warning message in coupled temperature-electrical-displacement simulation for Sintering

Abaqus error/warning message in coupled temperature-electrical-displacement simulation for Sintering

Abaqus error/warning message in coupled temperature-electrical-displacement simulation for Sintering

(OP)
I am making a coupled temperature-electrical-structural model for Spark Plasma Sintering. I have used abaqus standard.

The model worked for simple geometry involving only 3 parts (2 punch and die), but it is not converging for my original model which has 2 punch, sample, die, 4 spacers.

The error that I am getting is -

Too many attempts made for this increment

There are few warning messages aswell

1. Displacement increment for contact is too big

.2. SURFACE INTERACTION "interaction name", ASSOCIATED WITH ONE OR MORE CONTACT PAIRS WITH SURFACES HAVING UNDERLYING ELEMENTS WITH ELECTRICAL, TEMPERATURE, AND DISPLACEMENT DEGREES OF FREEDOM, DOES NOT HAVE ANY ELECTRICAL INTERACTION DEFINED. NO ELECTRICAL INTERACTION WILL OCCUR.

I used SI units and applied a pressure of 5 MPa at the top of upper spacer.

Can anyone help me ?

I have attached the input file here
