Hello,
We are trying to model a chrome plating process with a non-dissolving (inert) anode. We used the Tertiary, Nernst-Planck module with a moving mesh. We set up the electrodes as "External Depositing Electrodes", one for each of the cathode and anode. We are having trouble setting up an appropriate solver. At the moment, the solver uses two steps: (1) Current Distribution Initialization and (2) Time-Dependent Solver. For the first step, we are not able to achieve convergence with as many as 100 iterations. We have it set to a PARADISO solver. The messages on the log read as follows:
Nonlinear Solver
Number of degrees of freedom solved for: 28577
Nonsymmetric matrix found
and then it shows the results for the iterations.
We are also having trouble with the second step, where it keeps saying that the mesh is inverted, and thus, it does not proceed any further.
Any suggestions for which solver we should be using? Has anyone attempted a similar plating process?
