If I run both of them alone they work fine but when I try to couple them, the solution does not converge and the convergence factor switches between 1.39e8 and 2.79e8 without giving any error or results.
Initially it gave the error of convergence and singularity mentioning
Repeated error test failures. May have reached a singularity.
Time : 0
Last time step is not converged.
Then I changed the timing to microwaves heating for one day and Darcy flow for another day following microwaves heating. Results were obtained from both the models in coupled form but when I again tried to change the microwaves heating time to one year and Darcy Flow time to two years following Microwaves heating it started switching between two high values in the convergence section and did neither give any error nor results.
This model works fine for the case of heating less than 7-8 days coupled with Darcy';s flow. I have even tried to change the mesh size but the problem could not be resolved.
Can anyone suggest some thing?
