<span style="font-family:Arial,Tahoma,Verdana,sans-serif">Hi, Neks!</span><br style="font-family:Arial,Tahoma,Verdana,sans-serif">
<br style="font-family:Arial,Tahoma,Verdana,sans-serif">
<span style="font-family:Arial,Tahoma,Verdana,sans-serif">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? <br>
<br>
</span><span style="font-family:Arial,Tahoma,Verdana,sans-serif">And how each surface is assigned value "iside"?</span><br style="font-family:Arial,Tahoma,Verdana,sans-serif">
