How to modify postChannel in a way that it can be applied for a square channel
 

hi everybody,

I wanna modify the postChannel utility in a way that I can use it for a square channel. one of the limitation of postChannel is that it assume that the mesh is periodic in the x and z directions. In my case, I have just a periodic condition in z direction. I wanna plot rms velocities on a line for example placed at x=0.1.

Here is the postChannel.C

my problem is that I know what to do but I don't know how to do!!!!! :confused:

Is anyone here who knows from where I should start and how can I modify this utility?

any hints or tips would be appreciated.

Regards,
Mostafa

Hi，adambarfi. Have you got the way to modify postChannel to duct flow？

hi Niu,

I couldn't do it, so I just left it and did the calculation by myself :(

Dear Adambarfi,

How did you do the calculation? I couldn't find a way to do it in Paraview.

I did it using a c++ code, I got the data using sample utility and then I calculated the rms velocities using that code

I can imagine how tedious running sample for each grid layer cross-section would be.

I guess such volume averaging can be done in Tecplot, but have no idea how. Have you tried Tecplot? or anybody else?
