[Nek5000-users] Question about iside value

[nek5000-users at lists.mcs.anl.gov]

Hi Elizabeth,


userbc is called only for "v  " BCs (for velocity) or for "t  " (for temperature),


or other similar BCs that require user input.   "W   " BCs do not get passed

to userbc, nor do "O   ".


"o   " BCs do, however.


The rule is that lower case characters indicate user-defined values in userbc.

There is no lower case Wall BC, however.    Note that "W  " is effectively the

same as:


 "v   "


with ux=0, uy=0, uz=0.


Paul

Subject: [Nek5000-users] Question about iside value


Hi, Neks!

I am working with a complex geometry witch was built in gambit. I want to know a parameter "iside" for each of faces ( outflow, inflow and all walls) on zero step. If I ask in userbc ( in *.usr file) write "iside", I receive only iside=1, that matches inflow. It means that faces with type "wall" don't have "iside" value,am i right?

And how each surface is assigned value "iside"?

Best regards,
Elizabeth
