  My study includes the investigation of sloshing water in an elevated tank
  It always corrupts due to Dynamic mesh
  (DP 0) Update-Dynamic-Mesh failed. Negative cell volume detected.
  Or Floating point exception
  These were my setup for transient and fluent
  Transient
  
  Fluent
  
  Whats wrong with these settings ?!

  I’m not a Fluent expert. The one time I did a VOF model, after Initialization all the cells are filled with Phase 1. I had to Patch the cells that I wanted to start with Phase 2 before starting the simulation. I don’t see you doing a Patch operation. For example, if the tank is half filled with water, then you would patch water into the bottom half of the cells, leaving air in the top half of the tank.
  Also, it seems like you have selected to top face of the cube as both a wall and an outlet, which might be a mistake.

  Thanks for being interested
  I did Patched the bottom cells
  The top face is a Pressure Outlet
