I have a simple water setup: water flowing into a basin. In edit mode, I can see the wireframe of the water, but once it is rendered, I don't see anything. What is going on here? Here is my .blend
There are two distinct problems with your water not being renderable, one for the viewport preview other for the final render.
- Viewport - In the viewport the water simulation is invisible because it's Maximum Draw Type is set to Wire - Under the Properties Window > Object Tab > Display Panel change the Maximum Draw Type from Wire to Solid or Textured
- Final Render Your domain is set to non renderable in the outliner - Go to the outliner and set it renderable by clicking the camera icon
