Hello, I'm fairly new to ParaView still but I have one problem I'd like help solving.

I have volcanic eruption data (simulated) with x, y, z points and a concentration of ash at each of those points, per time step. This is in 2- and 3-D

I want to calculate the sum of that concentration within a box both above and below the vent of the volcano. So two boxes.

I need help/instruction to create these 2 boxes and which filter to apply that would calculate the sum of the particles in each box. It's likely a simple solution, I just can't quite find what I need from the menu's.

Also, I'm decent with Python so if you think the solution can be completed using Python, let me know!
I also have the guide if you know of a page number that I should go to.

Thank you for any help!

So does anyone have any idea about this? Even if it's simple, I'll take it! Maybe a tool or filter that can calculate/sum values within certain areas of a 3D grid?

Do you need more info to understand what I'm trying to get at?

Thanks!

One option you could try is data selection: http://www.paraview.org/Wiki/Data_Selection

Another one is clipping. You want to have a box and the clipping filter allows to select a box. The python code to do it is:

clip1 = Clip(Input=your_data_in_pipeline)
clip1.ClipType = 'Box'
clip1.ClipType.Bounds = [xmin, xmax, ymin, ymax, zmin, zmax]
clip1.InsideOut = 1

InsideOut = 1 => the points in the box will be left and the points outside the box will be cut out.

Same procedure for the second box:

clip2 = Clip(Input=your_data_in_pipeline)
clip2.ClipType = 'Box'
clip2.ClipType.Bounds = [xmin, xmax, ymin, ymax, zmin, zmax]
clip2.InsideOut = 1

On the clips you can apply the Calculator to calculate the sum of the particles.
