Hi,

I am currently playing around with dynamic mesh where I attempt to simulate a tube like structure, which should simulate a valveless (or impedance) pump. I get results which look reasonable by eye, but I feel that Fluent should not be happy with inlet becoming an outlet and vice versa (It does complain about reversed flow, but doesn't stop convergence).

Does anyone have experience with this? Is there something horrible and unacceptable I am doing here?

I normally set up inlet boundary (where I set certain time varying velocity which coincides with the mesh motion), and set another boundary as an outflow.

Thanks for your time.
