#### 3.12.3.1 Constant Body Force

This constant body force per mass is defined as a 3D vector. Each component can be associated with a load curve to define a time dependent body force. Only the non-zero components need to be defined. This type of body force is spatially homogeneous, though it may vary with time when associated with a load curve:
<body_load type="const">
<x lc="1">1.0</x>
<y lc="2">1.0</y>
<z lc="3">1.0</z>
