Hi, I am a Student and don't have much experience with COMSOL.
I want to simulate the pressure and stress on a pipe (like a very tiny syringe needle). The pipe itself is very thin and the material has to be gold. The fluid (Propanol - laminar) comes with high pressure and has got a diffrent temperature than the pipe.
I tried some tutorials, but haven't found any information about the effect the fluid-flow has on the pipe. I hope someone can give me an idea how getting started.
Best regards Eddy
