Meshes for simulations are often required to be conforming, non-selfintersecting, have elements of good quality, … In short, meshes have to be of good quality and intact. The goal of this project is to provide validation cheks for two- and three-dimensional meshes as well as algorithms to repair broken meshes.
This project is currently unassigned.
The student should be familiar with C++ and template programming.
We envision milestones, each containing its own list of tasks to be completed to be able to claim the assigned salary.
Getting familiar with the ViennaGrid
mesh data structure library
Implementation: Generic algorithm which tests if a segments are disjunct and if each cells in a mesh is also in a segment (is each cell in exactly one segment?).
Milestone is already finished
Implementation: Generic algorithm which tests self-intersection of meshes. Implementation for triangular 2d and tetrahedral 3d meshes required.
Salary: EUR 600
Implementation: Generic algorithm which tries to heal self-intersection of meshes and segmentations (remove dublicate elements).
Implementation: Algorithm which checks for holes in triangular 3d hull meshes.
Salary: EUR 400
Implementation: Algorithm which fills holes in triangular 3d hull meshes.
Salary: EUR 600
Milestone 5 (Optional)
Implementation: Algorithm which checks the orientated segmentation of a triangular 3d hull mesh (is each triangle in exactly one or two segments? if a triangle is in 2 segments, does the orientation differ?)
Salary: EUR 500
