Laminar flow and Transport of diluted species

Please login with a confirmed email address before reporting spam

Hi all! I am new to comsol and I am simulating flow of air+acetone in and out of a chamber. For this,I am using transport of diluted species and laminar flow physics. But I get the error of insufficient initial conditions. Can you tell me what all values are needed to be specified apart from the following?

Transport of diluted species

Transport properties->model inputs->velocity of the mixture

Initial values->concentrations of both

Inflow->concentration(boundary condition)

Laminar flow

fluid properties->density,dynamic viscosity of mixture

initial values->velocity field,pressure

inlet->velocity(boundary condition)

outlet->pressure(boundary condition)

Thanks in advanced :)
