Boundary layer characterization

klilla · February 5, 2009, 10:57

Dear All,

I'm trying to write a post processing tool to characterize the boundary layer. I created a cutting plane, where I would like to define lines for integration. How can I extract data from a 3D mesh over a line.

Thanks,

Lilla

Hi Lilla,

maybe I did not got the full complexity of your problem. If the first step is extracting data along a line, this is easy: Use the sample tool. Read the doc/UserGuide.pdf Chapter 6.5 'Sampling data'.

Hello Daniel

My problem, that I need to reach inside my code the data on the line. If I use the sampling utility, i will have them in distinct files. However, I try to find back, how the sampling utility extract the data, so thanks for the idea.

Dear All,

I defined a cellSet and I would like to know, if I can use the volumeIntegrate just on this set of cells.

Thanks,

Lilla
