Dear Openfoamers,

I would like to simulate a discharge problem inside a cylinder, so the flow condition and all the boundary conditions are axisymmetric. But i want to get such a result that the arc is attached to a certain angular position instead of a uniform attachment on the whole circumference.

I have heard that on can add a random perturbation function to achieve that, for example in my situation , a perturbation on temperature. But i really don't have any idea how to achieve that using OpenFoam, could someone kindly tell me how to do that?

Thanks in advance,

Bests,

Peng

Hi dear Peng,

Have you managed to do so? I need to add a random perturbation function too, any ideas?

Thanks.

Hi,

I want to add perturbations too. I was wondering if you managed to do that.

Thanks.
