Reply To: Negative Cell Volume detected in Dynamic Mesh.

Default settings for Unified Remeshing work for almost all cases and rarely need to be modified.

From what I understand from the screenshots, the plate is clamped on the left side, but are the sides of the plate (front and back from our view) touching any other faces? If so, those faces should be set as deforming. 

If the fluid domain extends further (through the front and back from our view) than the plate, then you shouldn't need any additional DM zones.

The paragraph that you quote would apply if you were using Methods-based remeshing, so you can ignore that.
