CAESER II Cnodes not working no forces at node in restraint summary?

CAESER II Cnodes not working no forces at node in restraint summary?

CAESER II Cnodes not working no forces at node in restraint summary?

(OP)
Hi Guys,

I am modelling a section of pipework that is connected to a nozzle on a heat exchanger vessel with the aim of checking nozzle loads with and without a spring hanger. In order to account for the thermal expansion of the vessel I have modelled the exchanger as rigid elements fixed to an anchor at the vessel fixed support. The pipework then proceeds from the rigid elements as normal.

My problem is that I have defined another rigid anchor at the nozzle connection as a cnode but I cant seem to get the forces in the restraint summary? (see attached Jpeg)

Nodes 10-60 define the rigid elements with an ANC at node 10

Nodes 60 onwards define the piping with an ANC defined at node 60 but 601 in the Cnode box.

When I pull up my restraint summary I am expecting to see values in X, Y, Z etc at node 60 but they are all 0? the displacements however seem to be working and these have non 0 values at node 60.

Am I doing something wrong here?

Thanks for your help!

Kind regards,

Nick

Hi,

I had not changed the next node to be starting from 601 and it was still connected to 60.

This appears to have been the problem.

Cheers,

Nick
