How to fill up every part of a geometry with a fluid? While fiddling around getting the letter F filled up by a fluid for an animation, I don't get the fluid to reach the horizontal parts of the F.
So far I´ve tried:

Domain resolutions: 32-128
Effector thickness: 0.2 (it leaks!) to 1.5 (its so thick the fluid runs over the entire letter)
Varying the size of the flow source

Tried it now it just leaves me with no visible fluid after baking at all.
Pretty much the same way as if I´m adding a new fluid simulation to any existing work. Don´t know if this is a bug or what not because whenever I apply a fluid simulation during a work it doesn't show any fluid. But when I do the same in a new project (so that the fluid simulation is alone) it works.
Switching from All to Replay on the cache displays the fluid but it doesn't behave the right way.

Select your 'F'

add solidify modifier




move solidify modifier before fluid

bake fluid again (by the way, i use 80 as resolution (much quicker to bake))


and you get:
