[Getdp] extracting data on mesh nodes that belongs to a line

[michael.asam at infineon.com]

Hi Brahim,

the output format NodeTable in GetDP's PostOperation should do what you want.
The line has to be a real line in your geometry with a physical group for referring it
in the PostOperation.
Here comes a small example showing the usage and creation of tables. 
For your case, just look the PostOperation "H_Nodetable".
I hope, it is of some help.

Cheers,
Michael

Subject: [Getdp] extracting data on mesh nodes that belongs to a line

Hi , i'm a PHD student and i am working on an NDT technic based on electrothermal phenomenas. Currently ,I'm using getdp to simulate a nucelar defect case. I wanted to extract power density value over a line of my conducting domain. I used the following command  :

       x0 = (odef/2+(0.10712e-3/2)) ; y0 =pdef ; y1=-hp+pdef; z0 =0;
       Print [ roj2, OnLine{{x0,y0,z0}{x0,y1,z0}}{nbDivs}, File "Line_roj2phex.pos"] ;
       Print [ roj2, OnLine{{x0,y0,z0}{x0,y1,z0}}{nbDivs}, File "Line_roj2phex", Format Gnuplot] ;

Using this , i have interpolated values aver the chosen line. My goal is to have only values over the mesh nodes that belongs to the line (without interpolation values). Is there a way to do this using gmsh ?

Thanks,

Brahim
