I´m currently doing a little fluid sim and the area of my domain is bigger then the object itself. Anyone know how to fix it? enter image description here

A fluid domain will always enlarge around the mesh to be a world-space referenced bounding box (@Gorgious commented), so what you could do to avoid extra voxels is:

  1. Rotate the fluid sim with the domain in the same orientation as the world.
  2. Run and bake the fluid sim to mesh.
  3. Re-rotate the sim back into the desired position.
