Good morning to all,
Whlie running the caesar model, i am facing one error. Below you can see the error massage:

FATAL ERROR # 362
PIERCK - routine BUILDD, Vessel longitudinal direction length found to be zero.

My model includes abovegroung and underground portions and nozzle along with tanks. I have checked all the elements and i couldnt found any element with zero measurement.

I am using Caesar-II version 5.10. My model is based on B 31.4

Please tell me the solution.
