Hi,
In multiphaseInterFoam, surfaceTentionForce() function, gradient of alpha definition is Code:
*( fvc::interpolate(alpha2)*fvc::snGrad(alpha1) - fvc::interpolate(alpha1)*fvc::snGrad(alpha2) ) I know in first case we have an alpha per phase, my question is about origin of such a definition. |

Actually i want to couple VOF with level-set based on multiphaseInterFoam solver. can i define gradient of psi field (level-set field) in similar way?
 Thanks in advance, |
