Fluid simulation not baking I am trying to bake a fluid simulation in Blender 2.67. Here is a mockup of my scene:



My scene is set up just like the picture, with a sun lamp above a mesh that is supposed to be a riverbed.

The liquid Domain object encapsulates everything except for the sun lamp, and it covers all edges.  Inflow and outflow objects are specified, one each, with the inflow velocity set to Y: -1.0, Z: 1.0.  All liquid simulated objects are enabled.  The mesh is set to Obstacle.  Settings are very, very low:  25 resolution for final and preview, 4.0 second start/end span for 100 frames (real-time), and smoothing set to 0.0, for a whopping 463 KB estimated memory space.

My issue is that when I try to bake it, after specifying a valid directory, nothing happens, except that the status bar appears, my computer saves the baked cache correctly, and then it's as if nothing happened.  Nothing in the menus changes, preview and render both act as if the event never occurred.  I'm also using Windows 7 64-bit with Intel Mobile Express Chipset Family 4 (graphics card).

That's not a lot, so I know it can't be my memory or graphics card issues.  Here is the relevant .blend file. What could the problem be?
I don't use the fluid simulator much but it seems the problem can be fixed by adding some depth to the inflow object. Currently it's just a flat plane. Just extrude it a bit on the Y axis and bake.
