[Paraview] Integrating drag and lift over time

[Moreland, Kenneth]

Sanjeeb,

You could click File → Save Data and then save the result of the Integrate Variables filter as a CSV file. After the file dialog you get another dialog of options. Check the box marked "Write All Time Steps" and click OK. You should get a CSV file for every time step in your data.

Subject: [EXTERNAL] [Paraview] Integrating drag and lift over time

Hello:

I have transient simulation results that I read into Paraview. I would like to calculate drag and lift at each time step. I have the normal and tangential wall stresses output at every time step. How do I accomplish this ?

For a given time step, I understand that I can use the sequence of filters

Extract Boundary surface -> Generate surface normals -> Multiply stress by area -> Multiply by normals -> Integrate Variables Filter

How do I get this drag and lift output written out at each time step ?

Regards,
Sanjeeb Pal
