Vlasov-Poisson model solver

This simulation of the Vlasov-Poisson system dimensions uses

• NuFI algorithm
• deal.ii FEM package

---

dimensions: 1x1v

notes:

• Locator not optimized for 1d.
• works for higher dimensions
• locator up to O(dim * Max_depth)

status: Working

Refinement working:

• grid versions saved on a vector
• solutions point to a version of the grid

todo:

• add ions
