Fluid simulation not baking with fluid object I've been having a little bit of trouble getting the fluid simulator to cooperate with me.

I have a relatively simple scene setup with plain rectangular objects that are scaled to realistic sizes.

Here's a rough idea of what I'm trying to accomplish: (Ignore the background dirt and grime, I'm just trying to show the scraping action on the machinery.) 

My plan was to use the fluid simulator and animate the membrane material moving forward and having the top liquid layer scraped off on the edge like in the example photo.


For some reason, the fluid simulator will not bake correctly and change to a liquid. The domain just remains a rectangle.

I've tried: 


Making the domain bigger or smaller 
Changing the resolution and fluid
world scene units
Double checking that scale has been applied to all objects
Changing directories for where the baked files are stored
If I just create a small fluid cube and put it inside of a larger cube set to be the domain, I can bake that for whatever that's worth.


I've got a blend-exchange file posted with everything pretty much set to defaults for simplicity.


Let me know if there's any more information I can provide.
The size of your fluid is too small in comparison to the domain size. There are multiple solutions: Increase the resolution of the fluid (in the domain object), increase the size or dimensions of the fluid (that large, thin rectangle), decrease the size of the domain or a combination of those.
