Fluids simulation unusable when scaled up the 3D Container

I'm learning to use fluids and the 3D container and everything works as expected at the container's default size. But when I scale up the container beyond a certain size (maybe 3x or more), either by using the scale tool or the the Size attribute for the container, the simulation completely breaks down. Any of the following might happen: no fluid at all is seen when I play the animation, only parts of the emitting object or surface produces fluid and in strange ways, performance slows down dramatically, other unexpected behaviours.

 

Is there something I'm doing wrong? What's the proper way to scale up the 3D container? The default size is extremely small for real-world dimensions where 1 unit = 1 cm.

I've done some more testing and it looks like you can't emit fluid from an object that's larger than the default size of the 3D Container (I've scaled the container to ensure it fully envelopes the object). And, unfortunately, I can't find any way to make it work at a size larger than the default 10cm 3D Container cube.

If I were you I would use the Bifrost Graph much much better solvers than the old 3d fluid container and easier to use for stuff like this + is procedural.

Thanks, I will look into Bifrost.
