Hello,

I'm simulating a laminar two phase (VoF) flow on a trickle bed reactor and I'm placing a source term for a tracer which is transported using the phaseScalarTransport pluggable solver.

Now, a plateau in the tracer concentration is reached as expected, but it is obtained by a sudden change in tracer outflow instead of a smooth approach to 0. How can this disconinuity be explained?
