[Q] Remove jagged edges in Fluid Sim

BL 2.78
OSX 10.11.6

Im trying to do a fluid sim, where fluid fills up a letter. I understand the basic know but keep bumping into jagged edges on sloped obstacle edges. (see screen shot). Know i read that you can bump up the Surface Smoothing but you will also loose detail then. I also still see the jagged edges when i go from 1-3

Is there any other method for sloped edge and smooth outcome without loosing to much detail in the sim?
