I need to use the Nozzle Flex option in a model, but I also want a solid connection to my vessel mock-up. The nozzle flex element (nodes 3110-3115) needs to have one end free, however, so I have run a weightless ridged (Nodes 3060-3115) through it to the next element (Flange 3115-3120). Does this sound like an accurate way to go about things? I've attached a picture of the area in question.

Better this way:

- define an element (weightless rigid) from vessel cenerline to vessel shell (e.g from 10000 to 10010), define the nozzle flange - rigid element (e.g. from 10 to 20) then nozzle pipe (e.g. 20 to 30).

At node no 30 specify a nozzle and specify the node 10010 as vessel node.

Anchor with cnode. I don't have access to Caesar right now so I can not show you. Maybe you can understand from the sketch below:

Ok, I have Rigid (3060-3150 in -y direction), pipe element (3110-3115 in -y direction), and Flange (3115-3120 in -y direction). I have the nozzle node defined as node 3110 and Vessel node set as 3150. If I'm reading your instructions correctly i should set my nozzle node as 3115, but when I do that the pipe segment sinks into the vessel... Is my pink nozzle graphic pointing it the right direction?

Wouldn't an anchor attache that part to ground? Or does the Cnode change that?

the cnode change this. it will show the relationship between the two nodes.

Regarding the nozzle, it should be defined in 3110 but specify in the nozzle dialog that 3150 belong to the vessel. The pink element is only graphic, sometimes it create some confusion.

So an element to element connection will work fine too, right? That is what I am using at the moment.

Thank you for your help! I was pretty sure my original method was not the best way.
