When ploting contours of the film temperature, thickness and mass without checking "Filled" option, should they all look the same?
I am having a case where contours of film mass and thickness show there is film formed in some areas of the domain, but those areas are not shown in the contour of film temperature.

Those images look different to me. I'm not sure what you're asking, please rephrase the question.

Thanks Rob, I try to clarify.
It is a case where initially there is no film present in the domain and it forms as air condense. At the end of simulation when ploting contours without "Filled" option, I suppose it shows (highlights) areas where film do exist there.
Looking at contours of "film thickness" and "film mass", some areas around the middle of domain are highlighted (dark blue) and I conclode film exist there (minimum thickness and mass, but stil film do exist there). But those areas are not included in contour of "film temperature"!
My question is why is that so? pictures are contours of different quantities, but if contour of film mass and thickness indicate there is film in that area, why the area is not highlighted in contour of film temperature?

The non-filled option will show the contour bands, replot filled to see what's not shown. What is the second image above showing?

The second image was the [filled] contour of "film thickness" before starting the calculation. So my understanding was that dark blue indicated zero film thickness [film do not exist yet, which is no surprize].
Looking at the same contour after the run, whole domain is highlighted. My question is regarding the areas in dark blue; According the contour legend, film is having 4.11 e-8 m thickness in those areas, if thats right, then why non-filled contour is not showing [all of ]those areas as well?
I am also attaching the contour of "film temperature" with filled option checked. As you can see, it is showing same temperature for all areas, despite the difference in color. That was the reason I tried the "non filled" option, to see where are the areas where film exist.
I am not sure if I am misinterpreting contours, your comments are appreciated.

Think about what a contour is, and what the line means. If the value is constant, or within the contour band, will you see a line?
