This is a simple version of the Caldera - Rio mesh domain
with 6 stacked surfaces, no refinement layers, single material
There are 3 face sets, bottom (1), top (2), and sides (3)

There are no 0 volume elements.
There are no degenerate elements (0 length edges).

This one is just a toy problem.
The units could not be set for the simple version, the cell sizes are too big.

The 5 materials represent 5 layers defined by input surfaces.

The fourth and fifth layers, block 4 and 5 are the upper units and TK
The third layer, block 3 is mostly TSF and Tk
The second layer, block 2 is mostly Pal
The first layer, block 1 corresponds with Pc

Stacked Layers: 6
Number Elements:         411600
Number Nodes:            497538 
Elements per layer:      82320
Nodes    per layer:      82923
