the term (2/3*mu*div(U)) in the N-S equation
 
Recently, I modified the rhoPimpleFoam to calculate the fluid flow and heat transfer in the compressible flow. But I can not find the term:2/3*mu*div(U) after checking all the files of rhoPimpleFoam. Could anybody tell me the location about the definition of this term in OF. Thank you in advance!
