Hello Im solving a coupled problem that has turbulent flow and reaction, to certain values I obtain negative values for concentration, but I see there is a lower limit after calculation of ep and k variables from turbulent flow (that´s reasonable), after reading the documentation I see that this lower limit is applied after calculating the variable, so I add a lower limite below the calculation of c (concentration varaible) but this deactivates the previous lower limit (for turbulent flow variables).
So my question is: It´s possible apply only one lower limit???
By the way adding the concentration variable in the lower limit list for turbulent variables seems work fine, but still want to know if thats the correct form of doing this or not.
