Hello everyone
I'm trying to run a biphasic problem with interFoam solver in which the inlet varies with time. Starts with alphaA=1 (that is, only component A flow) and after a few seconds only component B is fed (that is, alphaA=0).
In Time-varying boundary conditions of cfd.direct have the following option: “one and zero: constant one and zero values”
Can someone help me to define this boundary condition?
Many thanks.
