Hi
I am coupling the electric current module with the laminar flow module, to solve the flow generated inside microdroplet due to the electric field.
I want to apply the coulomb force =charge ( Q)* electric field (E) as a volume force in the laminar flow module
please help me overcome this issue
thank you

Hi,

the volume force is charge density . E

Cheers
Edgar

do you mean

ec.rhoq*ec.Er for r component
ec.rhoq*ec.Ez for z component
do you mean ec.rhoq*ec.Er for r component ec.rhoq*ec.Ez for z component
