Specific cell volume in paraview

Katt · August 23, 2017, 08:59

Hi,

I would like to select a specific cell using "SelectionDisplay Inspector" in paraview and would like to know the volume/ area of the selected cell in 2D/ 3D respectively.

I tried the intergrate Variable but it gives the entire volume of the domian rather than cell volume.

Can anyone help me here.

Apologies;

Found the solution here using "Python Calculator"

In addition to the python calculator as mentioned by Katt in this thread,

The Filters > MeshQuality also returns same result. Use the Volume dropdown option in Hex Quality Measure or Tet Quality Measure in the properties window of the filter. CAVEAT: If the mesh is composed of both hex and tetrahedrons, then I am not sure if it works...

this gives me a syntax error..... here is a screenshot...

also I need to extract another ratio from the cell volumes, how can I do that? I used calculator but the array is not there... Only Vc array is there...

Hi,

the Filter "Cell Size" calculates the cell volume. Same filter can be used for getting the area in case of a surface as input.

Hello community,

this may work for someone:
1) using topoSet and foamToVTK extract as vtm series the region
2) import it into paraview and apply filter cell size
3) open spreadsheet and check both Cell Data and Field Data. The first one shows volume per cell, the last one shows the total volume of the vtm series.
