I am modeling a 15,000 gallon horizontal water tank. The tank
is supported on two saddles. The tank is not pressurized. How do I
apply fluid pressure on part of the tank?

- Basil,

Thanks for your reply. I am able to apply a uniform positive pressure to all faces of the tank, but I don't think this is how the water actually acts. This method applies an upward force on the top of the tank that isn't there. I need to apply a nonuniform pressure down the sides and bottom of the cylinder, but haven't been able to figure out how in Cosmos. In other words, the water should apply a pressure that increases with depth on the cylinder.

George

- George,

Use the Nonuniform Pressure Loads. See the Analysis of a Fuel Storage Tank at CosmosWorks tutorial.

If you want to perform the structural analysis of your tank, paying attention on the water force, use a distributed load with the pressure equal to your one.
