Computational Electromagnetics with the RBF-FD Method
Andrej Kolar-Požun, Gregor Kosec
One of the most popular methods employed in computational electromagnetics is the Finite Difference Time Domain (FDTD) method. We generalise it to a meshless setting using the Radi…

Oscillatory behaviour of the RBF-FD approximation accuracy under increasing stencil size
Andrej Kolar-Požun, Mitja JanÄiÄ, Miha Rot +1
When solving partial differential equations on scattered nodes using the Radial Basis Function generated Finite Difference (RBF-FD) method, one of the parameters that must be chose…

The role of porosity in the transition to inertial regime in porous media flows
Dawid Strzelczyk, Gregor Kosec, Maciej Matyka
In this work, we investigate the fundamental physical mechanism of the transition from Darcy to inertial (Darcy-Forchheimer) regime in steady-state flows through porous media, with…
