Hello everyone. I am new with code_saturne and working on dc electric arc now. I have done a lot of research but still don't understand how to set boundary conditions correctly. I will very appreciate it if someone can generously sent me a simple example case of dc electric arc for reference or give me some practical advice on how to write codes of boundary conditions setting.
Here are the example images of the mesh and boundary conditions used in my simulation.
Hello, Yvan.
I have set relevant boundary conditions on the mesh and then on the GUI., but it didn't work. The simulation result was not what I want. Then I searched on the forum and someone said that boundary conditions can be set with .F90 files. Sadly I basically know nothing about Fortran. So it's difficult for me to write codes.
Also I think there's might be something wrong with my model's initiation. I did all the setting with GUI. Will that be enough? Or I have to do something with initiation.F90 file?
You can find example electric arcs boundary conditions files in the SRC/EXAMPLES file of your case, but I recommend using the GUI to the maximum (you can combine the 2, using the GUI for most definitions, including most boundary zones). There s also an optional C routine for another part of the BC, so I do not recommend this.
If the results are not what you expected, there can be multiple reasons, so, detailing the problems here will be more useful than switch to user subroutines.
I will very appreciate it if someone can generously sent me a simple example case of dc electric arc for reference or give me some practical advice on how to write codes of boundary conditions setting.
So it's difficult for me to write codes.
