Research Interests

** Making Unstructured Tetrahedral Mesh aruound complex geometry:

I'm interested in unstructured grid algorithms which can enhance the CFD applications of the flow over complex geometries.
Unstructured gird has more flexibility of adding or deleting points arbitrarily from the computational domain , mainly adaptively from the flow solutions.

Delaunay Triangulation Method


** Parallel Unstructured AMR Scheme in qsp configuration :

Aaptive mesh refinement(AMR) is an advanced numerical technique gaining popularity in the scientific and engineering computing community for solving large-scale computing problems.
The use of AMR techniques can significantly improve computational efficiency, and computer memory efficiency, by devoting finite computing resources (CPU time, memory) to the computational regions where they are most needed, making it possible to compute an accurate numerical solution with much less computing resources comparted to the use of a global fine mesh.
