convrting Foam v1.0 to Foam v1.6
 

Hello all,
I am trying to convert a previous solver and associated files from version 1.0 to version 1.6 but it seems that there were a few files in the old version that are not in the newer version of OpenFoam.The exact file names are listed as follows,
1.fvPatchFieldFields.H
2.physicalConstants.H
3.movingFvMesh.H
4.readEnvironmentalProperties.H
I would like to know what files these might correspond to in the newer version of OpenFoam or at least where to begin possibly?

Thanks for any help in advance,
Kyle L
