fluid pressure modelling

fluid pressure modelling

fluid pressure modelling

Hi Chaps,

Im using V5R6 to model a fuel tank but im having problems with the FEA side.

Ive tried modelling a simple hollow cylinder that is clamped at the base just so that i can grasp the FEA concept for fluid representation

in the generative structural anaylsis ive setup parameters to use in a formula for the pressure i.e. density - gravity and height in the tank.

so two problems i have:
first, i dont think im correctly setting the height parameter that i need to drive the equation - i created a height parameter using a length parameter with multiple values for different heights i need to analysis

secondly and most importantly - the results im getting show the max pressure at the top of the model rather than at the bottom - obviously with a fluid in the tank max pressure should be at h=base of the tank. ive tried so many ways to get the software to recognise that max pressure is at the base but ive had no luck

if anyone could have a go on their computer and let me know where im going wrong id be extremly grateful - deadline is coming up and im starting to flap!!!!!
