Hi,
I am using ABAQUS/CAE for analysing the effect of temperature on the natural frequency of cylinder. I have a cylinder having static fluid inside it. I have used acoustic elements for modelling of static fluid. Now, when I give the pre-defined temperature field to my model, the pipe is expanding but I can not observe any expansion in the fluid. Also, the frequency should decrease with increase in temperature but in my case, it seems to increase. Is there any other boundary condition which I need to apply?
Currently, I have used TIE constraint for holding the fluid inside the pipe. Is there any way by which I can also hold the inlet and outlet boundaries of fluid?
