Hi all,

New to these forums. I am working on writing a code to convert a structured grid to an unstructured grid. I have a PLOT3D ASCII format of the structured mesh grid.
Does anyone have any insight on how to do this conversion?

Almost all kinds of unstructured mesh format is made up of the following parts:
1.The number of nodes, the coorndnate of nodes.
2.The number of cells, the edge list of cells(ie. number of nodes which make up the cell).
3.The number of boundary faces,the edge list of bounday faces. the boubdary condition of the face.

that's all what you need to generate from structured grid.
Regards.
