[Getdp] Nodal temperature field

Hi,

sorry for my late answer.
Regarding node values you can also export the result as a node table in the PostOperation:

Print[temperature, OnElementsOf Omega, Format NodeTable, File "temperature_at_nodes.txt”];

Regarding the normal flux you can multiply the flux vector by the normal vector, which is
given by the build-in function Normal[] -> see manual: 6.2.6 Miscellaneous functions.

Regards,
Michael

Thanks a lot Ruth, that's works.
Do you know how to compute the integral normal flux of the temperature in a specified boundary ?

Best regards.

Hi Hamid,
The program computes actually the nodal values. It is just a question of post-processing.
The interpolation per element is done when calling the post-processing.
You just have to modify the post-operation:

PostOperation{
  {Name Fourier; NameOfPostProcessing Fourier;
    Operation{
      Print[temperature, OnElementsOf Omega, File "temperature.pos”]; // T is interpolated on elements
      Print[temperature, OnRegion NodesOf[Omega], File "temperatureOnNodes.pos”]; //T given directly on nodes
    }
  }
}

Regards,
Ruth
