This directory contains the sources and mesh files for the tutorial [SCL-12: Electrostatics]. It uses finite element methods to compute the electrostatic quantities based on a give intial boundary conditions and charge configurations. The tutorial provides code to get the solutions for the electrostatic potential due the the presence of charge at the interface. Additionally, as part of the post-processing calculations, the tutorial also provides the amount of total charge on a surface, the internal energy density, and the total internal energy of the system.
Meshes are generated by Coreform Cubit. Here is a sample Journal file to create a suitable mesh:
