turbulent energy dissipation rate
Hello,
i have a hopefully simple question for using UDF. I try to implement a new coalescence kernel for PBM. This contains the turbulent energy dissipation rate epsilon. I am using: eps = C_D(cell, tm); turbulence model is RNG k-epsilon. I get a SIGSEGV The fl process could not be started. I know its about epsilon because error does not occur when using eps = const. what do i have to consider? Do i have to save epsilon? Thank you. |
Update:
As i told I am using RNG k-epsilon model, where epsilon should be saved. What i did not considered is the "dispersed" option, which is only calculating epsilon for primary liquid phase. So I changed my code in Aggregation kernel into: epsi = C_D(cell, tp) with: */ Thread *tp as primary liquid phase */ Additional information: Theory Guide uses epsilon(liquid phase) for prince&blanch aggregation kernel for bubbles as well. No error occurs! Does anyone know if this approach is valid? thanks |
