In the code of my solver(not for postprocessing), I want to compute the contours of the flow field(e.g. pressure or velocity). I knew that VTK has vtkContourFilter and vtkMarchingCube for contour computing. How can I do it with these two classes?

Thank all.

Hi,everybody.

How can I achieve the special mesh and field values needed by VTK? I want to use them for further contour computing using VTK.

Thanks.

foamToVTK?

If you want to interface directly to VTK have a look at the Paraview reader module $FOAM_UTILITIES/postProcessing/graphics/PVFoamReader/vtkFoam/
(not trivial though!)

Btw, the utility 'paraFoam' is only a simple script which can be found in 'OpenFOAM-1.1\bin'.
Then in which way are the mesh and flow field convered to the datatype needed by paraView?

I think you will find it much
 

I think you will find it much easier to add whatever functionality you need to foam instead of trying to use non-native vtk libraries. There is allready some isoSurface stuff hidden in the OpenFOAM source, you just need to dig it up.

Hi,Eugene de Villiers and everyone. What is the easy way to meet my demand?

What exactly do you want to accomplish by calculating the contours of the flow field anyway?
