Hi foamers ,
I have a question about setting mut and alphat file in the 0 directory . I checked rhopimpleFoam tutorial . In this case all values of mut and alphat on the walls are 0 . type mutwallFunction; ------> for mut value uniform 0; type alphatwallFunction; ------> for alphat value uniform 0; Also I checked kEpsilon.C in this source code I found a formula for calculating mut and alphat . mut_ = Cmu_*rho_*sqr(k_)/epsilon_; alphat_ = mut_/Prt_; I want to create a case by coldEngineFoam . So I should set mut and alphat file and I am confusing about setting these files. Please anybody guide me. I should set uniform 0 for them or I should calculate them by using their formula . Why in the tutorial the values have set uniform 0 ?? I appreciate any help from you. Thanks and best regards, Sasan. |
