Need help solving coupling temperature and displacement analysis

I have three parts to model but once I determine the correct method I will be fine with the other two. The design is a simple C-Ring which I have used only half of it as its symmetric. It is in mm and I think I should put it in m just for ease. I have all the material data I could possibly get density, thermal conductivity, plasticity, elasticity & specific heat. I have made my step a coupled temp displacement, initally set time period to 1000, Nlgeom is on. I have made the load a negative surface heat flux on the step mentioned and may have to change it to m as the heat flux is appears to be too small for abaqus. The boundary conditions are fine. However the final boundary condition I have is a temperature BC of 1600 degrees C. This BC is on the step, not sure if it should be on the initial. The mesh is a hex coupled temp displacement. Just wondering if someone could tell me if im going wrong somewhere or whether i should switch to metres insead.

Any help really appreciated. Can send on the part file or screen shots if needs be.

Sounds like you are doing it right. If it does not work, then try switching to SI units (just to make sure you got the units right).
