Structured to Unstructured grid

Sen · March 2, 2011, 08:30

Hi,
Is there any possiblity of converting a structured grid to an unstructured grid. I "ve meshed an airfoil with C -type grid and it is structured and I just want to try an unstructured type on the same.

Sure it is:

1. Create a list with all your mesh points.
2. Create a mesh with your mesh quads, the vertices that compose a quad should be listed in say clockwise order.

A typical 2D unstructured grid looks like this:

1 x1 y1
2 x2 y2
......

1 v1 v2 v3 v4
2 v.......

Where you have a list with your vertices (x,y) coordinates and a list with the quads of your mesh.
