Fluids simulation went crazy I have a problem with fluid simulation.

The project is pretty simple, I have just a domain object and an inflow object. 

The inflow object is supposed to start drop oilish fluid at frame #1100 and ends after 8 seconds.

It was working almost correctly until I moved the inflow object a little (inside the domain), after that it started to act in a weird way.

The inflow seems to behave if it was a long tube (instead of a little sphere) and the fluid seems dense and is not following the initial velocity settings.

As you can see in this picture that strange long melting tube is supposed to be a flow of oil sprinking in the direction (x, -y, -z).



I've already tried to delete the bake cache, restart Blender, using different OS (Windows, Linux and macOS), but with no luck.

You can download the project file here.
The problem appears to be due to the geometry of the Inflow object - it has a negative scale (-0.025). This causes havoc with the Volume Initialization of the inflow in the domain.

The simple solution is to select the Inflow object and simply press S-1Enter. This will 'flip' the scale of the mesh so that it is enclosing the correct volume.

Re-baking produces the following :



When using Volumes it's imperative to ensure the Normals are facing in the correct direction - in your case the negative scale resulted in them pointing 'inwards' rather than 'outwards', confusing the fluid sim.
