Visualizing geometry using Paraview

Forums code_saturne usage

Dear all,

I am using Paraview to visualize Code_Saturne modelling results and I would like to display the solid boundary surfaces. More precisely, I am dealing with some atmospheric dispersion cases and I would like to see the wind flow and pollutant dispersion around obstacles.
I am currently using some filters (namely: Extract Surfaces and Extract Cells by Regions) to do so but it is not really convenient when I have to deal with meshes composed of multiple blocks.
So I would like to know if anyone has a more convenient solution to my problem.

Thanks in advance for the answer.
Nicolas.

Hello,
You have several solutions :

  • either activate output of boundary post-processing under the GUI (or use ichrbo in usini1.f90), use the “Extract Blocks” filter under ParaView, and if your case is turbulent, use a threshold filter on yplus so as to keep only “wall” type boundaries and remove inlets, outlets, or symmetry.
  • Or use the usdpst user subroutine to extract exactly the part of the boundary you need (also requires “Extract Block” under ParaView).
    Best regards,
