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".

• pmdc.node, the level 0 node file;
• pmdc.poly, the level 0 poly file;

• pmdc.1.ele, the level 1 element file;
• pmdc.1.face, the level 1 face file;
• pmdc.1.node, the level 1 node file;
