Hi,


I have been trying to find a post processing utility that can integrate a variable data (volScalar) at specific portion of my domain.


Description: I have a 2d case. Within a specific zone, I would like to sum up all the variable data. I know how to do this with paraview's integrate variable. But I am looking for something generic I can run from my terminal to extract this information without the need to go through paraview.



Note that I already have the output files. Just need to post-process to get the required data from these output files. To mention, I have substantial output data and using paraviews integrate variables is also cumbersome.


Any pointers please,
Thanks!!

Hi,


Probably I did not explain my case better earlier and still looking for a solution.



I have a computational domain as shown in Fig. 1 and I am only interested to have data in the region marked in blue and not in red.



I am able to use topoSet to find cellIDs which indicate the cells enclosed in blue. I am stuck here. Which utility can I use to integrate the cell data within this cellset (this is analogous to patchIntegrate except that I am looking at a cellSet and not a specific patch). I already have the output files.



I can use paraviews integrate variables but I have substantially large ampunt of data and doing this every time step is hard. In this regard can anyone suggest or point out to any example.


Thanks!

this requires a little bit of coding:
if you know your cellID, i would suggest that you iterate over all cellID's in your domain and access and process only the cells that match that blue area.
you can define a data holder and then create an iterative sum of integrated scalars for each matching cellID.
