Caesar - II default for anchor stiffness is 1.0E12.Since we normally simulate the pump nozzle as an anchor point, I would like to know what is the acceptable value of the pump nozzle stiffness that I can use instead of the default value. I had tried using the stiffness of 1.0E6 and it gives me a considerable change on the nozzle loads but I am not sure if my data is correct. I would greatly appreciate if you could provide me something in this regard.
