  The performed magnetohydrodynamic simulation examines the importance of
magnetofluid evolution which naturally leads to current sheets in the presence
of three-dimensional (3D) magnetic nulls. Initial magnetic field is constructed
by superposing a 3D force-free field on a constant axial magnetic field. The
initial field supports 3D magnetic nulls having classical spine axis and
dome-shaped fan surface; and exerts non-zero Lorentz force on the magnetofluid.
Importantly, the simulation identifies the development of current sheets near
the 3D magnetic nulls. The morphology of the current sheets is similar to a
cylindrical surface where the surface encloses the spine axis. The development
is because of favorable deformation of magnetic field lines constituting the
dome-shaped fan surface. The deformation of field lines is found to be caused
from the flow generated by magnetic reconections at current sheets which are
located away from the cylindrically-shaped current sheets.
