Create new functionObject library

Jack001 · August 18, 2016, 13:57

Hi All,

I am looking to create my own function object that can be used to calculate some metrics during runtime by including my new function object in $FOAM_CASE/system/controlDict.

According to this page http://foam.sourceforge.net/docs/cpp/a00004.html this should be easy and so I need to implement "libMyFunctionObjectlib.so" in the same way that there is already an implementation for "libForces.so". Then I imagine I can modify an existing .so file and do what I need there, compile the new library and I'm done. The only problem is I can't seem to find these .so files!

I have tried searching using grep -r "libForces.so" $FOAM_SRC but I get nothing!

Any ideas?

You don't modify .so objects!!! you modify the source code and compile it to make your own .so object, then put the lib("libMyFunctionObject.so"); to your controlDict and that makes your possible to use your function object there.

Also it would be helpful to take a look at this thread:
