Hi,everyone
I,m working on modelling corona discharge in air with coefficient form PDEs and Electrostatics interface. I'm encountering the problem of numerical oscillation in the simulation area (unexpected negative values show up), but the solver does not give error massage about convergence. Did anybody encounter the same problem? The possible reason for it is that the mesh is not fine enough. I have tried to make the mesh finer, but the problems remain. I want to know whether there are more reasons for the problems. Any advice will be greatly appreciated.
Thanks in advance.
