Update the n != 0 Poisson solver, too (energy conservation?)
| logical sml_module::sml_use_loading_factor =.false. |
Marker particle distribution taking into account the local (configuration space) node volume, i.e. aim for uniform number of ptl/mesh vertex. Set .true. when using a mesh with very non-uniform resolution.
| logical sml_module::sml_use_pade =.false. |
Use Pade approximation for short wavelengths.
| logical sml_module::sml_use_simple00 =.false. |
Use simple 1D solver for the flux-surface averaged potential instead of PETSc.
| logical sml_module::sml_verbose = .false. |
???
| integer sml_module::sml_wedge_n =1 |
Simulate a wedge of 2pi/sml_wedge_n of the full torus.
| logical sml_module::sml_zero_inner_bd =.false. |
If .true., use Dirichlet boundary condition \(\phi=0\) for axisymmetric Poisson solver.
