How to have the Inlet and Outlet swap places periodically during a simulation?

whelAnd · May 3, 2018, 22:08

Hi all,

I have a problem whereby I want the fluid to flow from left to right in a channel, entering the channel from the inlet on the left to an outlet on the right of pressure zero, I then want the fluid to flow from right to left, entering what was the outlet to flow out through what was initially the inlet. How can I achieve this?

Hi,

This sounds like it can be solved either by swak4Foam or Function1 types of boundary conditions. The 3rd option you have would be coding a new boundary condition. Probably I would go for swak4Foam (groovyBC).

Regards,
Tom
