PLOT3D file conversion
Hello there,

how can i convert a plot3d grid file to a more simple connectivity file?

Thanks a lot

There is nothing simpler than a PLOT3D file:

you can only convert it to something more complex.

Yes but how can i produce the conectivity of the cells?

Re: PLOT3D file conversion
PLOT3D is a format for structured grids. The connectivity is implied in the j,k,l sequencing. A cell with j = 4, 4, 5 is understood to be connected to a cell with j,k,l = 3, 4, 5. There is no explicit connectivity table. If you want to build one you'll need to write a program to extract the info from the implied structure.

How exactly would you go about writing such a code (to get the connectivity from a plot3d grid which only has x,y,z coordinates and block numbers)? Any ideas or sample codes?
