I know when we use API 650 nozzle load calculation,during Error Checking CAESAR II will compute the radial deflection and rotation of the nozzle and these values are not included in the analysis and if we want to include these,we must apply these displacements to a CNODE that we attach to the nozzle node.
but i doubt that are nozzle flexibilities(computed stiffness during the error checking)which CAESAR II compute them included in the analysis or not?
and should i remove the nozzle bottom and input these stiffness or not?

thanks

Yes the nozzle flexibilities are automatically included by CAESAR II.
