Hi

I am new to CAESER software.

My Nozzle comes on top of a verticle pressure vessel.
I need to define like, height of the vessel is 5800mm in Y direction with circle lying in x-z plane of dia 2600. So, how do i define it?
Also, height of the stiffner and distance opposite to stiffener has to be defined... how do i go about it?

hoping for an early reply

what do you mean by "how do i go about it?" what exactly do you wanna do by CAESAR? modeling, calculation or what? please ask more precise

The vessel is designed as per PD 5500
the following data is required to be filled up
node : 10 (at node 10 is where the nozzle is)
Vessel type : 0 ('0' for cylinder")
Nozzle outer dia : 6.625
Vessel outer dia : 2600
vessel wall thickness: 10 mm
Distance to stiffner or head : (What should i fill here?)
Distance to opposite stiffner: (what should i fill here?)
vessel centreline direction Vx: 0
vessel centreline direction Vy: 1 (is it correct?)
vessel centreline direction Vx: 0

(Dimension of the vessel : length 5800 mm, diameter 2800, Vertical pressure vessel (verticle along Y axis) - the support is a uniform skirt at the bottom)

* by inputing distance to stiffner as 5800, i get the following error
"At node 10 a NOZZLE has been specified and the distance to stiffeners is less than the nozzle radius, or negetive"

Kuhlblitz.........go ask your mechanical department/equipment vendor about where the stiffner rings are located with referance to concerned nozzle. You can have them from equipment drawing as well.

Kuhlblitz,

You are on entirely the wrong track. Your mechanical department would be wasting their time locating stiffeners etc.

The data you are requesting information about enables Caesar II to calculate flexibility of a nozzle attached to the cylindrical part of the vessel. That's why distance to head, internal stifferners is important. It does not refer to nozzles on vessel ends such as elliptical or torispherical caps.

Either ignore any local flexibility and input displacements for your nozzle (or you could include the vessel as a 'pipe' element), or use some other software such as FE-Pipe to establish the actual local flexibility.

Thanks for the replies..

I kinda found the solution, but not sure.. is there any online help manual or instruction site for CAESER2 available?

All of the documentation is available from the Main Menu - pull down the "Help" menu, then select "On-Line Documentation".
