The bottles and nozzles were modelled as solids. Once the CAD model was created, these structural models were then discretized into small Finite Elements using tetrahedral solid elements. Appropriate loading conditions were applied on the nozzles after categorizing them into pressure, sustained and expansion load cases. This model was then analyzed using linear static analysis by applying appropriate material properties.

From the FEA results it can be seen that the stresses on membrane are higher than the allowable values for both feeder bottles and attemptor bottles. Design modifications were suggested and implemented in a re-run of the analysis to reduce stresses.
