Abaqus Explicit: difference in TEMP, STRESS and PEEQ computation between adiabatic and coupled

Hi,

I have the two following INP files for Abaqus where the only difference is that in one case I'm using a CAX4R element on the other case, I'm using a CAX4RT element. Solver has been changed from one case to the other one.
This is the only difference between both cases.

Simulation time is small, so that conduction is negligible.

BUT: results in terms of Strains, Stresses and Temperatures differs.
T = 164.1°C for CX4R
T = 323.9°C for CAX4RT

The difference is Huge, what's Wrong ?
