sedimentation tank with mixture model, laminar flow

hello my name is Andrew and I am Colombian.

The reason I write to you is because I am in a research project on optimization in the design of sedimentation tanks, then I'm applying computational fluid dynamics as a fundamental tool.

as the essence of sediemntadores is working with a continuous phase and a dispersed phase at the moment I'm running the model with "Mixture Model, Laminar flow" but I get an error saying that the matrix has values ​​of zero on the diagonal .

thank you very much, I expect an answer.

Hi,

I am at the beginner level of COMSOL(elementary school - kindergarten ;) ). I am wondering if you find your solution after years, as I am trying to develop similar model.
My problem is particle tracing. I am not sure, should I go through two modules of mixture model, laminar flow and particle tracing, or only with mixture model? As my concern is the movement of particles in water.

Look forward to hearing from you.

Best regards
Masoumeh
