Hello everyone,

I am trying to simulate VOF LES collision of two fluid jets. In order to do so I am simulating flow in the injector first, than I want to use the results saved in a text file as velocity inlet boundry condition for the main domain where the injection is about to happen in order to increase calculations stablity and reduce number of elements in a single simulation.
I made a selection which is made of around 4000 cell faces. I want to write the results in a txt file in such manner:

cell face coordinate x ; cell face coordinate y ; cell face coordinate z ; velocity x component for this cell; velocity y component for this cell; velocity z component for this cell.

I have problems with writing a formula in order to get the single cell face coordinates. Has anyone ever done such thing? I tried using for loop and XB[i][0] to itarate through all faces in the selection and get the x coordinate but I get numbers which doesnt make any sense.

The selection I made, from which I want to get the results is shown on the first picture as a gray circle inside the pink selection. I have also included a file which is contained in VOF LES tutorial, with x,y coordinates of every cell in selection with corresponding velocity components. I want to achive the same result but with x,y,z coordinates and x,y,z velocity components.

I would be thankful for all your responses
