Prescribing pressure Boundary Conditions at inlet IPCS

variational formulation
1

Hello all,

I have a very basic model of a pipe which is solved by the IPCS method. I want to have it pressure driven, however, I’m not sure how to set the BCs.
My question basically is: if I want to model flow through a pipe and have it pressure driven, so I dont want to prescribe a flowprofile at the inlet. How can I implement this with when the NS equations are solved through the IPCS method. I dont know what BC to prescribe in the tentative velocity step or how this actually works. I wasnt sure if during step 1 only the no-slip condition is enough?

Thanks in advance!
Cheers,
Jack

@jacktat, there is a demo for Navier/stokes with pressure driven BCS using Chorins method. You should be able to adapt this to IPCS.
