Classification: UNCLASSIFIED Caveats: NONE Hi Utkarsh,
That's great. That will eliminate the programmable filter part of my pipeline. You didn't happen to also pushed update to VTK/ParaView that will write the expression "sum(EQPS)" to a file that will work in parallel, did you? :) Thanks -simon -----Original Message----- From: Utkarsh Ayachit [mailto:[email protected]] Sent: Tuesday, July 22, 2014 3:43 PM To: Su, Simon M CTR USARMY ARL (US) Cc: [email protected] Subject: Re: [Paraview] get the sum of a cell or point variable (UNCLASSIFIED) Simon, As I am cleaning my inbox, I ran into this email. Since there have been other emails about this I'll skip your original query :). Just wanted to give you an update on recent developments in ParaView. We recently pushed updates to VTK/ParaView to allow you to use Python calculator to compute "sum" in parallel across all blocks in the dataset. e.g. for can.ex2, you can apply the Python Calculator and select "Cell Data", with expression "sum(EQPS)" the result array will have the true global sum. This also includes operations like min/max/mean etc. Utkarsh On Wed, Jun 25, 2014 at 11:21 AM, Su, Simon M CTR USARMY ARL (US) <[email protected]> wrote: Classification: UNCLASSIFIED Caveats: NONE Hello, Running in PV client/server mode, is there a calculator function that will add up all the values of a variable (cell or point variable). I can use the programmable filter to write a python loop to iterate through all the cell/point of the variable and add them up. But, running in a client/server mode, how would you store that value? Can I just add a single value (not array) to the data? If so, what vtk data structure shall I use to store a double variable? vtk.vtkDouble()? Or is there a way to write that value out to a file. Running it in parallel, how would that be handled?
