Engineer - Mesh generation of cardiac meshes at cellular scale

Context

The engineer will work in the context of the EuroHPC MICROCARD European project which will develop a simulation platform able to exploit future exascale computers and to simulate cardiac electrophysiology on models with micrometer resolution.

The detailed meshes of cardiac tissue that this project requires will have unprecedented size, ultimately in the order of 10^12 elements. To create such meshes, powerful parallel mesh generation software must be developed.

Missions

The engineer will be in charge of the development of the open source toolchain for the generation of 3D tetrahedral meshes for the project test cases. Starting from segmented data (voxels labeled as vessels, myocyte, fibroblast…) provided by project partners, this person will develop robust tools for:

1. Building tetrahedral meshes from 3D image voxels;
2. Data filtering and cleaning;
3. Explicit discretization of cellular domains by isovalue discretization and mesh improvement and adaptation (implementation within the parallel open source remesher ParMmg and the sequential remesher Mmg).
