Hello All,


Hope you are having a great day !


I have a query regarding printing out gas properties like specific heats at constant pressure and volume (Cp and Cv) to the output directories during computation. I am using OF V10 for my computations.



The functionObjects method is a cool way to print out any quantity of our interest to the output directory. Therefore, I created two new function objects CpT and CvT, which essentially prints out the product of specific heats and temperatures. I basically created two copies of the functionObject for Mach number and edited it wherever necessary and changed the mathematical expressions (please see attached my function CpT files).


After this, I went to the top level Make directory '/src/functionObjects/field/' and modified the Make/files so that these two functions were added to it. (also see my Make/files document attached)


After this, I did wmake on the top level directory to generate the library 'libfieldFunctionObjects.so' - the make was fine and worked well without any errors.


However, when I try to use the CpT function object it simply does not appear in the available list of functionObjects and I get the following error when I try to use it:


--> FOAM FATAL IO ERROR:
Cannot find functionObject configuration file CpT

Available configured functionObjects:
89
(
CourantNo
Lambda2

....
...
...)


Please, I would be extremely grateful if someone can point out where I am going wrong. Any suggestions, tips and pointers would be very useful please. Am I perhaps, missing some step during compilation of the functionObjects. Please not that I am not modifying the source code in the /opt/openfoam directory but I am creating a local copy in my $WM_PROJECT_USER_DIR directory to make the modifications and then only copying the libfieldFunctionObjects.so file to the source directory in /opt/openfoam


Thanks a lot and looking forward to your response !
