There is nothing simpler than a PLOT3D file:

you can only convert it to something more complex.

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.

hm86 is on a distinguished road
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?
