Gysela5D GYSELA5D: a code
GYrokinetic SEmi-LAgrangian in 5D


This page presents some results that have been obtained with the Gysela code.

Transport Barrier

A transport barrier creation was successfully simulated with the Gysela code. We developed a very innovative method to mimic in our simulations the external polarization of the plasma by Ion Bernstein Waves observed in experiments. The associated sheared flow allowed us to simulate for the very first time the creation of a transport barrier using a flux-driven, so called full-f gyrokinetic (5D) model.

Memory Scalability Optimisations

In this work, two tools were created to manage memory optimisation. One to help the developer to understand where are the memory bottleneck and the second to study the memory scalability of the code in offline mode.

Thank to these tools, we archieve a memory gain of 50% over large case run.
