Error with Packed bed Reactor model

If you have an idea could you please help me to figure out how to resolve the following problem with packed bed reactor model. I applied the packed bed reactor tutorial existing in comsol 4.3b with my reaction and parameters.
the difference is the catalyst (CuO/Cu), (Copper oxide) I'm using is part of the reaction.
the reaction is: CH4+4CuO=2H2O+CO2+4Cu
But the CuO/Cu is immobilized with the reactor as a catalyst. The file will be attached with this message.
the following is the error i got:
Failed to find a solution.
Singular matrix.
There are 1 void equations (empty rows in matrix) for the variable mod1.Cu.
There are 1 void equations (empty rows in matrix) for the variable mod1.CuO.
There was an error message from the linear solver.
The relative residual (0) is greater than the relative tolerance.
Returned solution is not converged.
Thanks in advance
