Hello all,

I am using interFoam for simulating a two phase extraction column. In this regard I have generated a VTK file which included time steps from 1,2,3,4,5,6,7,........70 sec. The time step increment is kept as 1 sec.
Now i am visualising it in paraview through the VTK file. Till now it worked perfectly.
But now i am trying get a profile of alpha.water over a certain section of my geometry. I tried to use "plot over time" after selecting the cells using paraview selection tool ("select cells").
Now when I pressed the "apply" button, i am getting the following error message

" Input and output data types do not match"
segmentation fault (core dumped)
I am uploading the images of my geometry and the selected parts.
Please help.

regards Vivek
