In the example to resize domain in z- direction, the new differential equation is defined as

dx[k*dx(Tp)]/Zscale + dy[k*dy(Tp)]/ZScale + dz[k*zscale*dz(Tp)] + Q/zscale= 0

What is the different if I rearrange the "zscale" factor and change the equation to

dx[k*dx(Tp)] + dy[k*dy(Tp)] + dz[k*zscale*dz(Tp)]*zscale + Q = 0

As explained in the Technical Note "Coordinate Scaling", the scale factor is divided out of the equation so that flux continuity will be maintained in passing between layers with different scale.

As long as "zcale" is the same in all layers, the equation you propose will work.

If you have different scales in different layers, then you must use the form with the scale divided out.
