Abaqus - Displacement increment for contact is too big when I apply a surface heat fluxen

I am trying to do a simulation of a model which consists of two steps (static general and coupled temp-displacement). However after applying a surface heat flux the job gives an error. (I tried to do it without the heat flux and the job finished completing). Could this error be due to units mistake in the heat flux or could it be another reason? Attached are screenshots of the error and some of the warnings that appear. Thanks in advance
