Concentrated point load term.
The load value must be given in form of a special material
parameter (name prefixed with ‘.’), e.g. (in 2D):
'load' : ({'.val' : [0.0, 1.0]},)
This term should be used with special care, as it bypasses the usual
evaluation in quadrature points. It should only be used with nodal
FE basis. The number of rows of the load must be equal to the number
of nodes in the region and the number of columns equal to the field
dimension.
\ul{f}^i = \ul{\bar f}^i \quad \forall \mbox{ FE node } i \mbox{ in
a region }
