Dear Foamers,

I have a question about customized function in ControlDict.

I used to use OF_2.1.1 and in my controlDict I added the following lines to use this customized function.

writeduc
    {
        type writeRegisteredObject;
        functionObjectLibs ( "libIOFunctionObjects.so" );
        objectNames ("ducSensor");
        writeControl     outputTime;
    }

And in the solver's source code, I added the sensor.H there.
It works well!

But Now I transferred to OF_4.1 and I did the same thing, OF gave me the following errors.

--> FOAM Warning : 
    From function bool Foam::functionObjectList::read()
    in file db/functionObjects/functionObjectList/functionObjectList.C at line 671
    Caught FatalError 
--> FOAM FATAL ERROR: 
Unknown function type writeRegisteredObject

I noticed in OF_4, they did the following change from the website: https://github.com/OpenFOAM/OpenFOAM...c36fbd9fe9f1e4

-            << "    and use the 'writeRegisteredObject' functionObject."
+            << "    and use the 'writeObjects' functionObject."

Therefore, I changed the "writeRegisteredObject" to "writeObjects", but I got the same error.

--> FOAM Warning : 
    From function bool Foam::functionObjectList::read()
    in file db/functionObjects/functionObjectList/functionObjectList.C at line 671
    Caught FatalError 
--> FOAM FATAL ERROR: 
Unknown function type writeObjects

Can anyone give me some help here?
Thanks in advance!!!

Best

Try to use
libs ("libutilityFunctionObjects.so");
rather than
functionObjectLibs ( "libIOFunctionObjects.so" );
because libIOFunctionObjects.so is decapredted in OpenFoam 5,6.
