Hi Foamers!

I am trying to simulate a microfluidics setup we are investigating.
The setup is composed of a microscopic channel running a dilute solution of cells of known size.

My assumptions are:

1) incompressible
2) laminar
3) one-way coupling

I came up with the following solvers:
icoUncoupledKinematicParcelFoam
(simple)ReactingParcelFoam


Could you please explain the difference between the two? is there is another solver which is better?

Another question: I solved my flow (without particles) using simpleFoam, can I take the results and use them as data for the lagrangian solver?

Thanks,
Adam

Hi Adam,

icoUncoupledKinematicParcelFoam sounds fine if you just have one type of particle that doesn't react.

You can take the results from simpleFoam and use the mapFields utility to use the steady state results as your initial condition in the lagrangian simulation.

Hope this helps!

Thanks Declan!
mapFields worked. Now I'm stuck with injecting the particles. (I posted a new thread)
