Hi Ali,
you can easily do that by implementing a UDS, user defined scalar; in it's definition, ignore unsteady and convective terms. Amir |
Hi Amir,
Can you elaborate your statement? How can we justify that unsteady and convective terms can be ignored for solving the laplace equation? (i need to find the change in electric field in my geometry) I think you know how my geometry looks like :P , I have to find the electric field in the rotor domain. If possible can you share the UDF with me? Thank you. -Mark |

"UDS" is "User-Defined Scalar" equation and is available in FLUENT, something like energy equation and totally different from "UDF"! In the process of enabling a UDS, you can manage the unsteady and convective terms. For more info, please refer to the manual. Bests, |
Hi,
Can we solve defined scalar in x, y, z direction separately (for 3D geometry) or how can we see the scalar values in x y z directions using post processing? Regards Tharanga |

For sure you cannot solve it separately, but if you want to see the scalar values in a specified direction, you can simply draw a line and plot the scalar values over it... Bests, |
Hey, Thank you for the reply. I have solved the laplace eq (3D) and I need to get surface integration over x y z direction (separately) . Is there any method for that? cheers
|
If I elaborate more, I cant choose from the drop down menu x-scalar values etc. Therefore, I'm struggling to find x y z values over a surface. Thank you.

With a user defined scalar, you calculate a scalar, not a vector.
A scalar does not have a x-component... So your question does not make any sense. If you solved an electrostatic problem, your scalar is probably the electric potential. Which component do you want? The x-component of the electric field? You should know the relation between those two. |
It is a homogenized flow problem. Ultimately, I need to solve laplace eqn (vector) with BC's . Yes, you are right but there is no other way (I think) than UDS method in fluent to solve Laplace. Please suggest me an alternative method. Thank you
|
You don't make clear why you need another way. What is wrong with the UDS method?
And are you sure you want a vector laplace equation??? That is very unusual. I don't know why a "homogenized flow problem" would lead to a vector variant of the laplace equation. |
Hi, Thank you very much for your kind replies. I solved it as three different problems in fluent. I got the results. :D
