    FEA Modelling of Rocket Nozzle

    I'm away from my laptop now but can send the constraints tomorrow, i basically just did the top edge (previously surface when modelled 3D), where the throat would be and had it fully constrained in X,Y,Z. But i understand from btrueblood's comment about it needing to be able to expand outwards...

    FEA Modelling of Rocket Nozzle

    yes sorry i did mean static pressure that's the one i did, ive also changed it to axissymmetric instead of 3D now, so would the only constraint by on the y axis so it cant move up into the rest of the nozzle?

    FEA Modelling of Rocket Nozzle

    I've got it fully constrained on the whole of the top surface, cos its a de Laval nozzle but I've just modelled the diverging part of it. Is this the wrong way to do it? and i dont have a structure this is theoretical just for a final year university project, so i dont have a whole rig im more...

    FEA Modelling of Rocket Nozzle

    Hi, I'm doing my final year project on FEA and using image decomposition programs. I'm modelling a rocket nozzle, and have done 1/4 of it with axissymmetric loading conditions with a pressure acting outwards. I believe it's loaded and constrained correctly however I'm having issues with...
