Hi Nathan, 

thank for the quick response! 

Unfortunately, I cannot update YT because I must use a particular version given on a cluster. 
I have already known about sp.quantities.extrema("temperature”) but was wondering if there is something similar to the argmax-command in order to specify for example argmax(“temperature”, axis = “density”).

Best,

Katharina

Hi Katharina,

This is a new feature in yt 3.3, if you're using an older version I'd urge you to update.

If you can't update, you can do:

sp.quantities.extrema("temperature")

To get both the max and minimum value.

Hi together, 

I want to find out, among others, temperature and pressure values corresponding to a maximum density value within a spherical volume. I thought about using YTSphere.max(…) or YTSphere.argmax(…) for this purpose. However, in both cases I get the Attribute error “ “YTSphere” object has no attribute “max” “ . 

What might be the error origin? Have I forgotten something obvious?

Regards, 

Katharina
