Nature of problem:
Program TSP simulates the phenomena produced in a solid dipolar sample submitted to thermal cycles while in an external electric field: dipolar orientation and thermal randomization are the two competing effects, the relative importance of which varies with the field, the actual temperature and the thermal history of the sample (i.e. the previous thermal cycles). The polarization, and the displacement current showing changes in the polarization, are computed by TSP to support theoretical predictions and to help experimental interpretation.

Solution method:
The differential equation of the detailed balance is integrated to compute the polarization. The current is obtained by taking the derivative of the polarization at the time.

Restrictions:
The number of sucessive thermal cycles is limited to 6. Unless sizes of 4 vectors are changed, the job must not simulate thermal cycles extended over more than 600 s.

Unusual features:
None in Fortran statements. On Modcomp II, we use a plot feature (TTOP below) that can be deleted by just suppressing one instruction (subroutine call) in the deck.

Running time:
Without plot feature for short test data MODCOMP II: 102 s, or IBM 370/ 158 : 14 s.
