In that case, try the clip filter and set the clip function. If you still get the wrong surface, invert it with the Inside Out toggle.
In the next version of ParaView there will be an "Iso Volume" filter that will look like the threshold filter but create interpolated cuts between two isosurfaces (or the mesh boundary). -Ken On 6/16/10 5:22 PM, "Mohammad Mirzadeh" <[email protected]> wrote: Thanks Ken, I have tried that. The problem is that contour gives exactly the opposite surface. That may sound a bit confusing, so let me explain. Suppose I have a cube, and I exclude a sphere from it. Now what I want to see is the parts of the cube that are outside the sphere. However, if I plot the zero contour of my level set, it just draws the sphere which is exactly the opposite of what I'm interested in!

I am working on complex geometries and the way I represent them is to use a level set function. Now when I want to see solid part of domain, I just use the threshold filter on the level set function and ask for wherever it is positive. The problem that I have right now is that threshold filter kinda creates a rasterized bject right at the solid-fluid interface. Is there any way you can have a rather smooth shape at the interface?
