PEMFC modeling
 
hi
i need help for this situation ??????????
iter continuity x-velocity y-velocity energy h2 o2 h2o uds-0 uds-1 uds-3 time/iter
V_stack = 0.900000 (V) ... V_open = 0.950000 (V) (single cell)
fcu: I_anode = 0.000000 (A/cm^2) ... I_cathode = 0.000000 (A/cm^2) ... dI_mea = 0.000000 (A/cm^2) ... dI_stk = 0.000000 (A/cm^2)

Error: divergence detected in AMG solver: species-0
Error Object: ()

Hi，there.I am doing a unsteady fuel cell simulation.And the initial values are steady simulation.Steady simulation results are reasonable,but the unsteady results are obviously not reasonable.I focus on the water content result.Could you please tell me why?much obliged.
