The curved Mimetic Finite Difference method: allowing grids with curved faces
Silvano Pitassi, Riccardo Ghiloni, Igor Petretti +2
We present a new mimetic finite difference method for diffusion problems that converges on grids with \textit{curved} (i.e., non-planar) faces. Crucially, it gives a symmetric disc…
Inverting the discrete curl operator: a novel graph algorithm to find a vector potential of a given vector field
Silvano Pitassi, Riccardo Ghiloni, Ruben Specogna
We provide a novel framework to compute a discrete vector potential of a given discrete vector field on arbitrary polyhedral meshes. The framework exploits the concept of acyclic m…
Modelling and design of FTJs as high reading-impedance synaptic devices
Riccardo Fontanini, Marco Massarotto, Ruben Specogna +3
We present an in-house modelling framework for Ferroelectric Tunnelling Junctions (FTJ), and an insightful study of the design of FTJs as synaptic devices. Results show that a mode…
Explicit geometric construction of sparse inverse mass matrices for arbitrary tetrahedral grids
Silvano Pitassi, Francesco Trevisan, Ruben Specogna
The geometric reinterpretation of the Finite Element Method (FEM) shows that Raviart Thomas and Nedelec mass matrices map from degrees of freedoms (DoFs) attached to geometric elem…
Efficient computation of Linking number with certification
Enrico Bertolazzi, Riccardo Ghiloni, Ruben Specogna
An efficient numerical algorithm for the computation of linking number is presented. The algorithm keep tracks or rounding error so that it can ensure the correctness of the result…
- formulation with higher order hierarchical basis functions for non simply connected conductors
Ahmed Khebir, Paweł Dłotko, Bernard Kapidani +2
This paper extends the - formulation for eddy currents based on higher order hierarchical basis functions so that it can deal with conductors of arbitrary topology. To this a…
