A class for specifying various parts of a continuum mechanics problem, Dirichlet node information (which nodes are in space in a solid problem, which nodes have fixed flow in a fluids problem), the body force (per unit mass) (usually acceleration due to gravity or zero), the traction boundary conditions, and the density.
