Hi, I need to modify the v
I need to modify the van Driest's wall-damping function in vanDriestDelta.C but I have difficulties to find out how ystar is defined?
What is the relation between yplus and ystar in FOAM?
Usually, ystar=rho*(C_m)^0.25*k^0.5*y/mu, while yplus=rho*u_tau*y/mu
If the van Driest's wall function
f= 1 - exp(-yplus/Aplus_) is indeed used in vanDriestDelta.C then in FOAM y/ystar = yplus
I will appreciate your comments on ystar in FOAM.
