Thnx for your suggestions for selecting wall boundary. I checked my ensight gold data in paraview and i found their exit boundary block but it includes all boundary and i cant separate the the wall bounday from boundary block. Extract subset option is also not activated. what changes should i make while making the geometry and defining boundary condition so that i see all different boundaries and can evaluate them separately. I use Gambit to genrate the grid and apply boundary conditions Kind Regards Mubashir > To subscribe or unsubscribe via the World Wide Web, visit > http://www.paraview.org/mailman/listinfo/paraview > or, via email, send a message with subject or body 'help' to > [email protected] > > You can reach the person managing the list at > [email protected] > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of ParaView digest..." > > > Today's Topics: > > 1. contour programmable filter (guillaume) > 2.
