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;" data-mce-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;" data-mce-style="font-family: Arial, Tahoma, Verdana, sans-serif;"><br style="font-family: Arial, Tahoma, Verdana, sans-serif;" data-mce-style="font-family: Arial, Tahoma, Verdana, sans-serif;"><span style="font-family: Arial, Tahoma, Verdana, sans-serif;" data-mce-style="font-family: Arial, Tahoma, Verdana, sans-serif;">Best regards,</span><br style="font-family: Arial, Tahoma, Verdana, sans-serif;" data-mce-style="font-family: Arial, Tahoma, Verdana, sans-serif;"><span style="font-family: Arial, Tahoma, Verdana, sans-serif;" data-mce-style="font-family: Arial, Tahoma, Verdana, sans-serif;">Elizabeth</span><br><br></BODY></HTML>
