  We study how turns and constrictions affect the resistive response of the
superconducting wire after instant in time and local in space heating, which
models the absorption of the single photon by the wire. We find that the
presence of constriction favors detection of photons of various energies but
the presence of turn increases only ability to detect relatively "low" energy
photons. The main reason is that in case of constriction the current density is
increased over whole length and width of the constriction while in case of the
turn the current density is enhanced only near the inner corner of the turn. It
results in inhomogeneous Joule heating near the turn and worsens the conditions
for appearance of the normal domain at relatively small currents when the
"high" energy photons already could create normal domain in straight part of
the wire. We also find that the amplitude of the voltage pulse depends on the
place where the photon is absorbed. It is the smallest one when photon is
absorbed near the turn and it is the largest one when photon is absorbed near
the constriction. This effect comes from the difference in resistance of
constriction and the turn in the normal state from the resistance of the rest
of the wire.
