Hi, I'm now post-processing on my 3D half annulus in the form of creating lines through the geometry (parallel to the Y axis) at regular axial intervals and producing x-y plots of the velocity, viscosity profiles etc. The geometry runs along the z axis, so I'm setting lines (surface>line/rake menu) at intervals along this which was ok until a certain distance along the z axis, where the lines are being displayed as just one or two dots. At further points along the z axis Fluent wont even create the line, giving an error. My coordinates for the lines are fine as far as I know (all I am changing after the first line is the z (axial) value) Any comments will be gratefully accepted!

Hi! We had problems with creating lines, if we had values from 0 to something and it worked, if we did it with 0.000001 to something. Dont ask me why. Yvonne
