This sound reasonable. By spatial resolution, I meant the something similar. Because the V_cutoff may depend on your grid resolution. But there is something else you should take care of: Imagine you...

Did you modify solidParticleI.H as well?
If so, I would say put the error you get here.
In addition, for cell center I guess you may simply use: "findTetFacePt" function or other functions like...

What is your dt and minimum grid spacing (dx)?
I guess it might be due to very small dt times dx in the denominator of momentum source resulting very large values.
