Mesh adaptation is the process of modifying a mesh at hand into one that will reduce the error of the simulation by adapting the mesh based on the characteristics of the flow. It is in the core of many Computational Fluid Dynamics (CFD) simulations and as such it is important to be efficient and robust. This project focuses on how to improve current tools both in terms of functionality and performance in order to enable efficient parallel mesh adaptation.
