Velocity fields For Model inputs in Transport of Diluted Species physics

Please login with a confirmed email address before reporting spam

I'm using electrostatics together with this module. I would like to relate the velocity field with the electrical field in electrostatics module, say velocity is a constant mutiply by the electrical field. Any instructions on how to do that? My feeling is the velocity should be a vector, so how to put a vector here?

Dear Zhumei Sun,

If I am not mistaken you are mentioning about Electrosomotic flow. If that's the case you can use laminar flow--> wall inteface--> electrososmotic flow--> and choose electric field in it. And couple it in velocity interface of transport dilute species.

Or if you want to specify just velocity . Then you can caluclate velocity using variables and you can specify it in velocity field.
