How can I get the smoke in the render to look like it does in the viewport? I am new to blender, I have smoke rendering problem please help me.
In viewport the smoke looking very nice and realistic:

 

But when I render it looks completely unrealistic and looks noisy: 



Please someone tell me how to fix this problem.
Increase the smoke resolution (divisions) and increse render samples,also set clamp indirect to something around 3. Check smoke high-res and experiment with divisions and strenght!
