Dear all,
I have a situation were I need to simulate a kind of tube with a pressure inside, the target is to calculate the displacement of the tube due to the pressure. Reinforcements are needed and these will be evaluated.
In the case of a round tube we can work with a 2D-axis symmetry study and put a boundary load on the inside of the tube and use 1 roller on the bottom, this is calculating fast and accurate.
Now I want to this in 3D (because my final tube is a none axis-symmetric shape (round rectangular)).
But in the 3D version I can not work without a fixed constraint or with too many rollers.
In fact this is the same just that the 3D version is not thinking that the applied force is completely symmetric.
I tried with splitting the rectangular tube in 2 and work with a symmetry but that did not work out neither.
Any suggestions on how to deal with this kind of problems?
Kind regards
Hans
