hi ,

We are in process of design water pump station with very big pumps ( 2800 cubic meter per hour @19 bar ). tHE FIRST QUESTION IS CAESAR is capable to simiultae the thrust on suction side and is it capable to simulate the thrust on suction side . We are considering tied expansion bellow but the raction looks very big on pumps nozzel . could you please advice

CAESAR II will not determine hydraulic loads. You will have to compute (or otherwise obtain) any thrust loads.

Once you have the load, you can apply this to a node representing the pump flange.
