I met an error when running the simulation. The simulation structure is a silicon pin junction with a graphene on the top of that. I used graphene material database from this file “Electro-optical modulator” from
I want to run the charge solver to see the results such as band structure, charge density, etc.
The error showing is that “Error (charge): Drift-diffusion solver failed to converge after 40 iterations, 0.365347(0.0001) remains. Error: there was an unknown parallel error. The error code is 9002, the process number is 0”.
I searched on KX forum, found the similar error and tried to alternate the charge solver settings, just like mesh min/max edge length, or global iteration limit, but there was still the same error.
The attached are the ldev file and log file describing the error. If there’s any question I have, please let me know. Thank you so much for helping me have a check on my file. Any suggestions are welcome.
