fedoo.weakform.DistributedLoad

class DistributedLoad(distributed_force: list, name='', nlgeom=False, space=None)

Weak formulation for a distributed load.

This weak formulation permit to define distributed loads and should be associated to another weak formulation (e.g. StressEquilibrium).

The recommended way to apply a distributed load is to build the corresponding assembly with fd.constraint.DistributedForce() or fd.constraint.SurfaceForce() and add it to the problem boundary conditions with pb.bc.add(load_assembly). The assembly is then converted to an equivalent Neumann boundary condition.
