liquid and gas boundary condition

annan · September 5, 2018, 03:06

Dear all,

I am pretty new to OpenFoam, and I want to know how to set the following boundary condition:
I have a liquid and a gas entering my domain from the same boundary, but they have two different velocities. I have tried to make a geometry with 2 blocks, thus 2 different inlets, one for the gas and one for the liquid, but setting velocities that are different results in an error.
Can you please help me figure out where the problem is ?

Thank you in advance.

What solver do you use?

Dear Jeneas,
Thank you for your reply.
I use interFoam as solver
