A null area is an area object which is assigned the None property such that it may be excluded from analysis, but used to apply area loads of type Uniform to Frame (Shell). For all other types of area loading, an area section with very small thickness must be defined, then assigned to area objects for the transfer of loading. This will ensure that loading transfers without the object contributing to structural stiffness. Ensure that auto-meshing is not assigned to these area objects, otherwise numerical problems may result.
