hello everyone,
I wanna know if this is possible using Fluent: Can we force fluent to change a velocity profil and make it more look like this: What i'm trying to do is actually to simulate the presence of plasma actuators... Thanks a lot for advance. More about plasma actuators are here: I know fluent is made to solve navier-stockes equations, i majoring in fluif mechanics, my knowledge in electricity is very limited. What do i need to simulate actuator ? maxwel equations ??? can we implement them via UDF ?? Thanks a lot again |

Defining velocity profiles with a UDF is quite easy.
The UDF manual has all the information you need. Concerning the plasma actuators: this is the first time I heard of this, but as far as I can see, it simply introduces a momentum source to the fluid. Again, such a source can be modeled with a UDF (search for DEFINE_SOURCE in the manual) |
