Component composition with DMol3

"

Hello,

I use DMol3 to run DFT calculations remotely on a supercomputer.

Currently I am investigating Cd/Zn Alloy system.  On the Materials Studio Visualizer, I managed to create the composition Cd 95%/Zn 5%, however, nothing in the .car or ,input appears to consider this composition and only Cd appears in the .car file.  Any idea how can I include this in the calculations?  Is there any other files need to be uploaded rather than the .car and .input files?
