NuFI_deal.ii/README.md

Vlasov-Poisson model solver

This simulation of the Vlasov-Poisson system dimensions uses

• NuFI algorithm
• deal.ii FEM package

---

How to use

Dependencies:

• deal.ii >= 9.6.0
• OpenMP
• perf + flameGraph (optional)

After cloning the repo to your machine cd into it and run:

mkdir -p build; cd build/
cmake ..
make
cd ..

Then check/change parameters.lua and run with ./build/nufi_poisson. If you want to run with a FlameGraph visualization at the end use ./run.

Further description

dimensions: 1x1v

status: builds, runs

notes:

• -O3 compile flag accelerated runtime about 100x
• Locator not optimized for 1d.
• Works for higher dimensions (to be tested)
• locator up to O(dim * Max_depth)

to-do:

• add ions
• for 1x2v add electro-magnetic
• test other f0 s
• test longer simulations with more plotted points
