Hello to all,

I have been given a project for analysis which has Fired Heater and Reactors. I am having some doubts on analysis of Piping connected to Fired Heater. Fired Heater is a box type and has inverted U-Tubes inside.
1. whether i have to model the fired heater? or else i can give the displacement at the nozzle and carry over the analysis?
2.I have got the Nozzle diplacements from vendor. It has been given dx=(+/-)75, dy=(+/-)75, dz=(+/-)75. if i have to give this as input then how i have to give displacements in both direction.

Please give me some suggestions on this, i have so many doubts on this, as i am doing with this equipment for first time.

Raja.
