Revisiting the diffuse layer polarization of a spherical grain in electrolytes with numerical solutions of Nernst-Planck-Poisson equations

These datasets contain the Comsol files that were used in the publication "Revisiting the diffuse layer polarization of a spherical grain in electrolytes with numerical solutions of Nernst-Planck-Poisson equations", which is submitted to the Journal of Geophysical Research: Solid Earth. 

Note:

1. file parallel plate_static.mph is the model used to generate numerical results in Figure 2
2. file parallel plate_dynamic.mph is the model used to generate numerical results in Figure 3
3. file grain_mechanism.mph is the model used to generate numerical results in Figures 4, 5, 6, 7, and 8
4. file grain_salinity.mph is the model used to generate numerical results in Figures 9, 10, 11, and 12
5. the solutions in the mph files are cleared to reduce file size. The solutions can be reproduced by conducting "solve"
