FumeFX for Maya
ver. 4.1  
  Render Warps  

FumeFX comes with Render Warps wrapper that allows users to apply Deformations such as Bend, Flare, Twist etc. to the cache. Weather you need to create a special effect or you have to tweak final animation, with Render Warps there are so much more possibilities. With just a few mouse clicks users can warp their cache files and watch result directly inside the Viewport, Preview Window or in rendered images.

This tool can be a life saver when minor tweaks are required but your project deadline does not allow more testing and simulation runs. With a simple Lattice Deformer you can easily adjust the fluid flow to match your needs. Example below shows an exaggerated deformation of the grid without producing any visual artifact.
