Hello guys, currently i am doing a simulation by using species transport...however, i have found that if i change the setting from steady to transient model, the concentration of one of the species at the outlet became relatively small (10^-250)...i was wondering is it species transport model cannot be applied in transient case? The settings of my case is shown as below:

Inlet 1: fluid A
Inlet 2: fluid B (Bulk species)

Output results (mass fraction of A) at the outlet:
Steady case: 0.5-0.6
Transient case: 0
