hi i am doing 3D diffuser problem. for postprocessing i need to draw some arcs and i want to know the vertex average on that arc.i am not able to find the method to draw arc in FLUENT.if anyone knows plz help me. thanx in advance..

From the Fluent main menu go to: Surface>Quadratic

Here you can generate arc shape surface for postprocessing.. Goodluck

HI JIM CLANCY THANX FOR U R POSTING. BUT I WANT TO DRAW JUST ARC,NOT SURFACE. MY MAIN AIM IS TO DRAW DIFFERENT ARCS(HAVING DIFFERENT RADIUS) AND TO KNOW THE VERTEX AVERAGE ALONG THAT ARCS.SO PLZ HELP ME RAGARDING THIS.WAITING FOR U R SOON REPLY
