solve diff equation

[altenbach]

No these are just images. Please attach your VI instead. How is the 3D graph configured?

You did not copy it correctly. You need to swap the inputs of the subtraction (top left).

You are doing 10*(x-y) instead of 10*(y-x). Big difference!!!!

(I strongly recommend to go with the version using arrays. Fewer wires! Fewer places to make mistakes!)

Sorry i'm out right now but i will return couple hours.. 

Even i made 10*(x-y ) not 10*(y-x  ) at least the graph shows something right ?

No! (With the swapped inputs It goes to Infinity in less than 400 iterations, and NaN afterwards)
