I can't seem to work out the proper sequence of filters for the following.
I have a 2D triangular mesh with a time-dependent scalar field, say phi. I
want to generate a single isoline, say phi=0, which I can do with the
contour filter, but then I want to generate a single point by intersecting
The equation x=1 is actually a plane in 3-space, not a line. So what you really
want to do is intersect your contour with the plane at x=1. You can easily do
this with the slice filter.
Next, select the resulting point with the select points on or select cells
on tool (in the toolbar buttons
