### Unstructured triangular meshes for tokamaks

Participants : Hervé Guillard, Alexis Loyer, Adrien Loseille [Gamma3 team, Inria Saclay] .

The construction of block-structured flux aligned grids that respect the magnetic equilibrium topology experiences difficulties in the SOL region of the tokamaks where the flux lines cross the material walls. As an alternative to the use of block structured meshes, we have studied the construction of unstructured triangular meshes using constrained anisotropic Delaunay mesh generation [16]. This work was also performed in the framework of the EoCoE European project (see section 8.2.1.1).
