I create a box domain, small sphere inflow and text letter converted to mesh as an obstacle. I want to fill the letter with water. After baking (tried several resolutions 75-220), the fluid flows and fills only up to the inflow source and the water won't get "pushed up" over this line.
In previous blender versions i would play around with the real world meter size param (which i don't see anymore in 2.8) and sometimes this would help but i really didn't understand what i was doing.
