Hello,

In interFoam.C I have commented out:
the PISO loop
the line: "#include correctPhi.H"
the line: "#include UEqn.H"

and I still see variations in the velocity field

I would like to run the Zalesak slotted disk problem which require a constant velocity field.

There may be alternative ways of running this problem with the original interFoam? In this case how to set a constant velocity field through out the simulation?

Could anyone help me with this?

Many thanks.
