Thanks for the suggestions, you are correct one end is fixed while other being pulled in X-direction.

Sir. I've tried the way you have mentioned above and it start working. Before reading your suggestions i have tried couple of things, like instead of applying Force i choose an option of Remote Force after which i saw the betterment in results but with tiny localization of stresses at couple of nodes. So what is the difference between Remote force and Force?

And Secondly,  when we apply the force by "Face selecting option" why we are having that tiny side-sway? Furthermore, when we apply the force on surface how that force being distributed at the surface ? Is that something (force/number of nodes)? Can that distribution of force can cause eccentricity which leads towards that sway?

I will soon upload the archive file.
