@ -5,3 +5,15 @@ It solves the Vlasov equation for ions in a 1D spherical domain.
Electrons are treated as a fluid either isothermal (Boltzmann) or polytropic.
Self-consistent electric field is solved using a Newton-Raphson method to solve the Poisson equation.
A 2D table linking T_e, n_e and the average Z must be provided. Examples can be found in 'data/TNZ'.
Input files for different cases are in the 'input' folder.
Files with the boundary conditions are provided in 'data/boundary'.
Input files must specify which TNZ table and boundary file are using.
To run the code execute
./vlaplex <path-to-input-file>
