July 26, 2017, 15:05	deltaN_ value in interfaceProperties used in interFoam solver	#1
Saideep Senior Member Saideep Join Date: Apr 2015 Location: INDIA Posts: 203 Rep Power: 12	Hi, According to interFoam's: interfaceProperties.C file available in the source (src), I am wondering whats the theory behind "deltaN_" value? Its defined as $deltaN_ = \frac{1e-8}{V^{\frac{1}{3}}}$ It should always be a minuscule value lower than $\nabla \alpha$ and its purpose is to avoid a floating point error. Why shouldn't it be directly 1e-8 (hard-coded) but includes a volume variable in the equation? I went through H.Rusche's thesis but this specific term was not discussed there. Any insights here?
