Fluid sim not working, no liquid is being made I've been trying to make a sim of oil flowing out of a pipe onto some objects I made for a school project. The problem is that no matter what I try, the domain doesn't seem to want to show up while it's baking. I've tried scaling up the inflow object and moving it out of the tube it was in and that didn't work. Then I tried changing another object into an inflow and still the domain doesn't create any liquid.







Earlier when there were less obstacles and the domain was smaller it did work.
All obstacles must be completely enclosed by the domain.  If not then the fluid won't bake. This quite often catches people out, me included.

I strongly encourage you to read the documentation at blender.org as it details what to watch out for in the Fluid Simulation section of the blender manual.  Good advice for any time you get stuck.
