Dear All,
I would like to smooth the graphics, like if I did not have discrete data, but splines. Mostly when I am ploting iso contourns...

Question: is that possible in paraview/paraFoam?

Thanks a lot

Does adding normals help (Filter->Normals)?

Thanks, It helped, but did not solved...
What I really would like to accomplish is producing good graphics (beautiful shadings etc...) even in a very coarse mesh...

I am still seeing piecewise linear objects, instead of a nice smoothly-shaded 3D contour... I would love to see something really like a spline interpolation, so that even in coarse meshes the graphics would be fine...

Thanks again,

hi luiz,

did you manage to accomplish the smoothing?

i'm now finding myself in the same situation.

I have just been in the same situation and I found a solution. During the starting of paraFoam such a case.OpenFOAM file is created and loaded. Now, in paraFoam open the file again, so that you have two sessions of it. One session should be the normal one and in the second session should only be used the patches which are intetended to be smooth by Filter->Alphabetical->Smooth.

Hopfully it will help; I wrote that fast here; ain't got no time.

Im interested in smoothing my geometry, as well.
Unfortunately in my case, the smooth filter is set in grey.
Any Idea?

Choose another color! ;-)

the Filter is greyed out!
nice joke! ;)

This is what worked in my case:
1. Extract Surface
2. Generate Surface Normals (-> delivers smooth output)
