Multilayer metal deposition

Hi, i am trying to simulate multilayer metal deposition using 'element birth and death' technique.

I have glued the three volumes ie substrate, layer1,layer2 as shown in figure. Then, i am trying to kill the layer2 to simulate the deposition of layer1. At last, i will activate the layer2 and apply the load on the layer2.

Am i thinking in the right direction?

There are 43 loadsteps in each layer so i am using do loop but, i am getting following error,

Where do i place 'ekill' command in my code??

i am attaching the snapshot of the APDL script after meshing.
