Gysela
GYSELA A drift-kinetic semi-Lagrangian 4D code for ion turbulence simulation. A new code is presented here, named Gyrokinetic SEmi-LAgragian (GYSELA) code, which solves 4D drift-kinetic equations for ion temperature gradient driven turbulence in a cylinder (r,θ,z). The code validation is performed with the slab ITG mode that only depends on the parallel velocity. This code uses a semi-Lagrangian numerical scheme, which exhibits good properties of energy conservation in non-linear regime as well as an accurate description of fine spatial scales. The code has been validated in the linear and non-linear regimes. The GYSELA code is found to be stable over long simulation times (more than 20 times the linear growth rate of the most unstable mode), including for cases with a high resolution mesh (δr∼0•1 Larmor radius, δz∼10 Larmor radius).

Graphene2020 has been closely monitoring global developments of the COVID-19 virus since the start of the year. The health and safety of our speakers, exhibitors, participants and staff is our number one priority. Due to the latest news and rapidly developing health concerns and risk to life caused by the spread of the coronavirus disease (COVID-19), organisers decided to postpone Graphene2020 – NEW DATES are: October 19-22, 2020.
The 10th edition of the Graphene Conference series, the largest European event in graphene and 2D materials, will be organized in Grenoble (France). Over the past nine editions, the Graphene Conference has strengthened its position as the main meeting point of the graphene community worldwide.
