Superimposing 2 Velocity fields For Model inputs in Transport of Diluted Species physics

Please login with a confirmed email address before reporting spam

Hi every one
Im Trying to use a superimposed Velocity Field which i did get it from solving 2 Laminar physics (I solved them in a Stationary mode) as the Velocity input in :
Transport of Diluted Species physics>Transport Properties 1>Model inputs
But there is a problem.it is not possiable to choose the both Velocity Fields together!Comsol only allows us to chose a specific Velocity Field from a specific study (For example i can only choose the main velocity field or Streaming Velocity field not both of them together.)
I want to know if there is a way to superimpose those velocity fields together and use them as an input for solving the Transport of Diluted Species equations.

Many thanks in advance for your help
Farzad
