How do you design a pump using Caesar to perform stress analysis?

I have designed vessels and heat exchangers but never pumps. I'm not sure how to start it off. So far I have anchored my connecting pipe and put in a rigid line from that pipe to the endiing lenght of the pump. I'm not sure if I should continue rigid to the side then up to the suction. Please help!

Model the pump as rigids from the anchor point (identify it on the dwg) to the suction and/or discharge flanges. You do not necessary need to have Suction and discharge lines in the same model. There are two tutorials in Caesar documentation.

Its all the same whether you model vessels or pumps in Caesar.As Dan suggested, model it as rigid elements with the diameters of suction & discharge sides adhering to the pump dwg (or even of larger dia{but no way lesser} than what is specified to simulate the rigid casing of pump).

The only important thing to remember is the fix point or the location for pump anchor. Do go through the pump dwg thoroughly to confirm the type of pump supporting-i mean whether its a centreline supported pump(central pedestal type) or off-centre supported or may be of some other type.

After ensuring the nozzle loads are within the acceptable limits;you also, ensure the pump & piping mating flanges are aligned within acceptable limits to avoid fututre issues at site related to pump alignment.

Don't forget to provide adjustable type of support as the first support on both the suction & discharge sides.

Hope this helps.

Thanks for your help.
