```python
from ansys.mapdl.core import launch_mapdl

# Launch MAPDL
mapdl = launch_mapdl()

# Enter pre-processor
mapdl.prep7()

# Create first block and mesh with tetrahedral elements
mapdl.block(0, 10, 0, 10, 0, 5)
mapdl.et(1, "SOLID187")
mapdl.vmesh("ALL")

# Create second block above the first and mesh with quadratic hexahedral elements
mapdl.block(0, 10, 0, 10, 6, 11)  # Ensure blocks do not touch
mapdl.et(2, "SOLID186")
mapdl.vmesh("ALL")

# Select elements at the intersection (assuming no intersection due to gap, this step is conceptual)
# In practice, you would adjust selections to identify near-field elements for contact generation
mapdl.nsel("S", "LOC", "Z", 5, 6)
mapdl.cm("CONTACT_ELEMS", "ELEM")

# Generate contact elements (conceptual, as direct API calls for generating contact elements may vary)
# This step assumes customization or additional logic to define contact pairs based on proximity or other criteria

# Plot the contact element pairs as a wire-frame
mapdl.eplot(show_node_numbering=True, line_width=1, background='w', show_edges=True, wireframe=True)

# Stop MAPDL
mapdl.exit()
