Default flow in a vibrating pipe
Posts: n/a
I am using CFX4 to model water flow in a vibrating pipe in order to couple with ANSYS result for fluid-solid interaction.

Here I want to consult for the question related to CFX 4 as follows:

Do I need to cut the period into several time steps and input the pipe shape every step to run static flow model? Or CFX with its routine can handle the flow of the whole cycle shape change in one program related to moving boundary to run transient flow due to shape deformation?

If it is the later choice, what I should to check besides USRSRC and a sliding grid?

Thanks very much and best regard
