Hi guys,
I wanna write a program that generates grid for a rectangular domain.I just need to define nodes (with arrays).actually a program that just reads nodes based on the lengths of rectangle and number of cells for each length.and then import it to PLOT3D.should I define all nodes inside the rectangle or just on boundaries?how can i define the connection between nodes? I don't know how to do it exactly.please help me.

Best Regards,

I don't know about plot3D, but if it permits structured grids, the easiest way is to make a structured grid, in that case you don't need any connectivity table.

first do a planar case and then stack it.
u need to define only the boundary points, and based on the number points on the boundaries u can generate points.

this is simple to do only thing is u need to write a gridgen program in 2d and generate the point list and increment the z co-ordinate to get the 3d one
