Rendering error in liquid domain

I bake a 18 Frames liquid simulation. (Fill up Glass letter with water).

The liquid simulation ran perfect. In Wireframe mode everything is perfect. But when I use render view in cycles,
2 Frames render only the half of the domain. I don´t know why.

Take a look at frame 214 and 216

I can’t look at frame 214 and 216 as you have only provided 211 and 212.

Are you using a boolean modifier? Or some other modifier? My guess is that you’re using a modifier downstream of your fluid sim that’s wigging out because of the high poly count and complex shape.

Or are there any coplanar surfaces, that is faces in the same place?
