Hello all!
I am trying to model a time varying mass source with reactingParcelFoam solver. I basically want to see what happens when the compactness of the source changes to the evolution of the species. For this I have removed the source which is computed from the evaporation of the parcels in the OpenFoam. I am trying to use fvOptions to multiply the source with sinusoid to make it vary in the time domain.

To add sin function, I am trying to add the sin(Time) to Su in the source file. I copied the SemiImplicitSource source files to my local working directory and then changed the file names to sineSource.C and sineSource.H and made changes accordingly everywhere including the Make folder. However, when I try to compile I get the following error
Code:
sources/general/sineSource/sineSource.C:38:18: error: redefinition of ‘const wordList Foam::fv::sineSource<Type>::volumeModeTypeNames_’

/home/sagar/OpenFOAM/OpenFOAM-4.x/wmake/rules/General/transform:8: recipe for target 'Make/linux64GccDPInt32Opt/sources/general/sineSource/sineSource.o' failed
make: *** [Make/linux64GccDPInt32Opt/sources/general/sineSource/sineSource.o] Error 1
I think that with the new sineSource type it is still referencing to the semiImplicitSource by the redefinition error. I am not so sure of it. I don't know whether any other changes needs to be made as this is a general source. Any help would be appreciated

Thank you
