Temperature increasing when unixial strain

Hello,

I have a question about the temperature when strain on the simulation box by NPT with temperature 1.0 , however ,the tempterature can not stay at 1.0 instead keeping increasing. Can some one help me on this ?

Am I missing something or am I doing something wrong in the input files? Any help is greatly appreciated.

Many thanks
