I disagree. This thread is about a package called simpleFunctionObjects which is not part of the OF release but of an addition called swak4Foam

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?

:confused:

Of course. If you can calculate the drag force correctly
