HelyxOS Boundary Conditions
I am using OpenFOAM v2.2.0 since a couple of weeks ago, and I am using HelyxOS to do the setting up of the case. The workflow is:
The problem is that I don't really understand all the Boundary Conditions options. I have been trying to find a document or so where they are explained, but I didn't find any...
Regarding the Velocity:
I can roughly understand some, but all which I wrote in Bold letters, I have no idea. And what is the difference between Fixed Value and Freestream? The Zero gradient is not completely clear either.
Regarding the Pressure:
Here I don't understand most of them... And if I want to set the atmospheric pressure in the boundaries, how can I do? Because I have to write a m^2/s^2 value...
It is a long and hard question, I guess... THANK YOU VERY MUCH FOR THE LITTLE HELP YOU MAY GIVE HERE :D
Hey There and welcome to the forum!
The best thing to do is look through the source code (especially the top of the .H files) for each BC and read the descriptions. If you have OpenFOAM correctly installed, you can go to

Thank you very much for the advice!
I have checked the .H files and, even if not in every case, they helped me to understand the boundary conditions a bit. I have also seen the PPT presentation; quite interesting. Anyway it would be nice to have some example where the BC can be usually applied; some seem very similar, but I know that the BC thing is very tricky... and I don't know if the results would change much; I guess that it may be so.
Again, thank you
