Basically every variable that is in memory. Check the output in directory 0.1 called foo then there is a variable foo you can exist. Of course fields that are not written are not found that way

There is a function object called listRegisteredObjects in swak4Foam/simpleFunctionObjects that gives you such a list. There may be similar FO in plain OF (but it wasn't at the time I wrote that FO). But to use that you'll have to install a full swak4Foam (sorry)

Thanks Bernhard. My bad, I thought simpleFunctionObjects are part of main OF distribution, not swak4Foam. Nevertheless I checked listRegisteredObjects and found the list.

However, I would also like to know which fields are written into memory, and can be used/accessed by the main openfoam functionObjects, such as probes, fieldAverages, etc. Some of my runtime post-processing functions are to be OF built-in features.

What listRegisteredObjects lists is exactly that: all objects that can be accessed by others with simple knowledge of the name (or as you say: fields in memory).

Probes for example are not in that list because they are instantiated by the probes-functionObject. They can not be accessed from outside the functionObject

Well, thanks again. I found another possibility before your reply, and that is the writeRegisteredObject. I tried it and can confirm that it generates the same list as listRegisteredObjects from swak.
I guess the next step for me is to add the fields I need to the createFields so that I can use swak on them.
Huge thanks by the way for this amazing set of tools you wrote. It makes working with openfoam a bliss for a C++ illiterate user like me.

Which OF-version? The writeRegisteredObject I have the sources to is used to write objects that otherwise wouldn't be written. It relates to listRegisteredObjects like "cat" (the command) relates to "ls"

Thanks.

Sorry for the delay. I used it on OF23x. The output were similar tables only with different formatting. As I remember they contained same entries.

My guess: the list of objects in the error message if you specify a non-existing object

Hello Bernhard,

Is it possible to write drag coefficient on the cylinder using the swak4Foam-or-functionObjects for non-newtonian fluids?

Of course. If you can calculate the drag force correctly
