Display boundary condition defined by UDFs
Hi Everyone,
I have problem this Fluent software. Because my boundary condition was defined by UDFs (parabolic profile velocity), I want to check accuracy it by interface graphic. How can I display it in the interface graphic of Fluent? Thanks in advance. |
Hi,
if your case is 2D, then your boundaries are lines, then from plot menu you can write data and check them. else for 3D cases, create a line over your boundary and follow above. |

Hi Amir, Thanks for your help. According to your instruction, I think that we only write data in the defined boundary condition when the solution is solving, isn't it? But I want to check this condition before we run the solution. Do you have other idea for this problem? Thanks. |
it doesn't need that your problem converged! you set boundary condition, so after some iteration you can stop solving and check.

Hi Amir,
That is good idea. I used this way to check accuracy boundary condition. But I faced new problem. Firstly, I ran some iteration and stopped it. Then I checked by display contour plot at inlet boundary. In this case, I can see that the boundary condition distributed parabolic profile. If I checked by display vector plot, the vector distribution is the same. What is some thing wrong at there? Thanks for your help. |
Hi,
that's right, probably because vectors belong to cell centers adjacent to boundary were solution didn't converge yet. as I said before, the best way is to use plot menu, for 2d case plot velocity along boundary and in 3D case, make a line over that and follow above. regards, |
meshing in Gambit
I want 2 know "How 2 define the ratio in gambit meshing?". Also, The First length,last length definations are....
|
@ Geth:
!!! the ratio is defined as the length of an element to adjacent previous. |
Hi Amir,
Thank your help. Best regards. Tran Toan |
