I'm trying to modify the existing k-epsilon in Fluent, but I always find some embedded hard coded algorithm that make any user-defined modification very hard. So I was wondering if I can use the laminar solver and add a UDS for k and epsilon, UDM for turbulent viscosity, adding the appropriate source terms for the momentum equation. Is this possible, or the laminar solver has some limitations or hidden hard coded setup? Many thanks, Javier
