Dear all,(adsbygoogle = window.adsbygoogle || []).push({});

I have some problems with a program called the simulation of laser interaction with materials. In this program, they asked for some parameters which I am unsure of but I believe it has something to do with space grid for simulating the thermal conduction. This is a 1D heat conduction simulation of laser heating on a semiconductor (a.k.a laser annealing).

These are the parameters that have asked for:

=========================================

NUMBER OF NODES 100

DELTA X (A) 200

DELTA X1 (A) 600

DELTA X2 (A) 1600

DELTA X3 (A) 4800

KX 70

KY 80

KZ 90

TOP LAYER NODE (L6) 10

MIDDLE LAYER NODE (L7) 20

=========================================

Can anyone help me with what delta x, delta x1, delta x2, delta x3, kx, ky and kz are for? The program uses a finite difference method for solving. Thanks.
