Base class for inter-particle stress models.
Exponential inter-particle stress model of the same form as used in twoPhaseEulerFoam.
tmp< Field< scalar > > dTaudTheta(const Field< scalar > &alpha, const Field< scalar > &rho, const Field< scalar > &uRms) const
Collision stress derivative w.r.t. the volume fraction.
label min(const labelHashSet &set, label minValue=labelMax)
Find the min value in labelHashSet, optionally limited by second argument.
