I have some questions 1) How can I see the coordinates of the mesh in fluent's display grid mesh option. 2)I have obtained the simulations results of half of the geometry assuming symmetry over axis. Now while plotting(x-y plot) I would like to have data in the whole region not in just half.

1) Not sure if you can plot out the co-ords numerically, but you can see contours of the grid x, y and z value.

2) Try Display -> Views -> Mirror Planes

Thanks for your response With mirror planes only I can see the contours but how to get the 2d plots. Also Is ther any example of User Defined Scalar proveded by Fluent. Regards P

Did you try and extend the axis of the x-y plot, if you did and there is no data, then I am sorry, but I don't know how to do it. You could export the data to excel or similar and mirror it manually - that shoudn't be too much trouble

I don't know of any examples for UDS. The best place to find info is in the UDF manual chapter 9
