Dear CP2K users/team,
I am trying to do QMMM simulation of diaspore surface as shown in figure
below. I want to do QMMM simulation using LINK atoms approach and I defined
top layer as QM and bottom layer as MM.

When I assign QM1 and MM, QM2 and MM as links in LINK section I got below
error.

But when I define link section with QM1 atom and MM atom only, the
simulation is running (may be not accurate) and also if I define QM2 atom
with MM atom only then the simulation is running. But when I define both I
get the error mentioned above.
Please let me know if you have any suggestions. Have a nice weekend.
Thanks and Regards,
Prasanth.
