Deflection of Hollow Cylinder filled with Water

[roldy]

I have a horizontal hollow cylinder (capped at both ends) that also has 5 disk supports inside the cylinder. The cylinder is fixed at both ends. The cylinder is filled with water. There is a shaft that runs through the cylinder also. I would like to know what the deflection of the cylinder is due to it's own weight and the weight of the water. I know that I should use remote mass for the water. The 5 disk supports create 4 compartments that are filled with water (the other 2 are empty). Do I have to divide up the mass of the water for each of the compartments? The compartments are not of equal length. So I would basically find what percentage each compartment accounts for and multiply the mass of the water by this. These values are the values I use for the inner faces of the cylinder for the Load/Mass (Rigid Connection). Is this correct? Attached is a zip file containing the SolidWorks file. It would be greatly appreciated if someone could take a look at this. I have never done anything with remote loads and would like to learn the correct way. Thank you.
