Ideal Mesh Generation for Modern Solvers and ComPuting ArchiteCTureS – IMPACTS

Submission summary

The rapid improvement of computer hardware and physical simulation capabilities has revolutionized science and engineering, placing computational simulation on an equal footing with theoretical analysis and physical experimentation. This rapidly increasing reliance on the predictive capabilities has created the need for rigor- ous control of numerical errors which strongly impact these predictions. A rigorous control of the numerical error can be only achieved through mesh adaptivity. In this context, the role of mesh adaptation is prominent, as the quality of the mesh, its refinement, and its alignment with the physics are major contributions to these numerical errors. The IMPACTS project aims at pushing the envelope in mesh adaptation in the context of large size, very high fidelity simulations by proposing a new adaptive mesh generation framework. This framework will extensively used the Riemmannian metric-field and will be based on a unique cavity-operator coupled with advancing-point techniques to produce high quality hybrid, curved and adapted meshes.
