 May 13, 2010, 15:27 plot bulk temperature of fluid #1 Member   mohammad Join Date: Apr 2010 Posts: 42 Rep Power: 7 Dear all we can get bulk temperature in Report>Surface integrals:change report type from Area to Facet average. with this way i get bulk temperature in inlet or outlet or... The problem is how can i plot bulk temperature in x-direction? There is no bulk temperature in xy plot!! Is there any way to plot and write bulk temperature in x-direction? thanks

at some distances from inlet, in facet you creat iso-surfaces along the length of your wall, you can use TUI to creat them or u may read a journal file containing the commands to creat all of them at same time,
iso surfaces are cross-sections where you want to calculate bulk properties,so they are perpendicular to your wall
