question about term representation
 
Hi all Foamers,

I have a doubt concerning a term representation. During the modelling of a flow problem where I have to account for extra tensions besides the normal newtonian stresses. That term is equivalent to a divergence of the extra tension, and enters in the momentum equations as a source term. I am planning to include the term in the form

fvc::div(extraTension), being extraTension an volume Tensorial field. However, is it more correct to include the extra term as Sp::(fvc:div(extraTension)), or is there any other option that suited to my situation?

Thanks in advance,

António Martins
