Hello, I would like to understand how to simulate a volume force (in my case I am trying to simulate electrotheral body force) in a microfluidic channel using laminar flow multi physics. I would appreciate if anyone kindly share any model similar to it or direct me towards the right procedure.

Thanks in Advance

Hello,

you can define a "weak contribution". The weak expession is for example Fcz x test(w) with a force Fcz that contributes to the velocity w. Note that x is a multiplication factor.

Best regards Michael
