How to compute the surface area of a isosurface plot ?

[balcieb]

Hi,
I have 3D temperature field data from a reactive flow simulation. First, I created a pseudocolor plot for the temperature field, then added the isosurface operator from the slicing section. In isosurface attributes, I set the N_levels=1, Minimum=2000, and Maximum=2200. Then, hit the draw. I assume this isosurface roughly represents the flame front surface. Now, I want to compute the surface area of this isosurface. How can I do this ? Thank you.

From the GUI:

Open Controls->Query
Find 3D surface area and highlight it. click Query.

From CLI:
ensure the plot you want is active.
the default output from a Query is a string, so change the output to Value

>>> SetQueryOutputToValue()
>>> results = Query("3D surface area")
>>> print(results)

Thank you very much.
