Examples and Tests:

PMDC is a piecewise linear complex (PLC) which describes a permanent magnetic motor machine, with 972 vertices, 502 facets, and 4 regions. To view it, type "tetview pmdc.poly".

The tetrahedral mesh of the motor is stored in the PMDC.1 files. To view the mesh, type "tetview pmdc.1".
