Does anyone know how to setup transient simulation of incompressible flow in a pipe of which diameter changes over time in SimScale? The pipe will dilate first for a brief period of time and then return to steady-state size.
I have successfully done steady-state and transient simulation of incompressible flow in a rigid pipe using SimScale. However, I do not know how to make the pipe diameter varying over time. I went through all boundary conditions but none was useful. I found some deformation projects in SimScale but they were for “solid mechanics”. I also found two posts in the forum about “Fluid-Structure Interaction” which suggested that SimScale didn’t have this feature yet at least in 2017. Is there any way to simulate incompressible with time-dependent pipe diameter in SimScale at this moment? If not, I may have to try other platforms.
Thanks in advance for your comments.
