13.278. SOLID278 - 3-D 8-Node homogeneous/Layered Thermal Solid

SOLID278 is available in two forms:

homogeneous (nonlayered) thermal solid (KEYOPT(3) = 0, the default) - see SOLID278 - 3-D 8-Node homogeneous Thermal Solid.
Layered thermal solid (KEYOPT(3) = 1) - see SOLID278 - 3-D 8-Node Layered Thermal Solid.
