Abstract
A study is made of the suitability of the continuous systems simulation
language CSSL-IV on the Cyber 205. In an earlier paper by the authors,
models characterized by parabolic and hyperbolic partial differential
equations were simulated using CSSL-IV. In the present paper, the model of
Faraday generator, which can be described by means of a pair of elliptical
partial differential equations in velocity and induced magnetic field,
is simulated.
The equal velocity and current lines contours have been obtained for
values of Hartmann numbers up to 20. No acceptable solutions could be
obtained for larger values of Hartmann numbers. In an attempt to explain
the source of inaccuracy, a mathematical analysis of the solution of
Poisson's equation, using CSSL-IV, has been presented. It is demonstrated
that a decrease in the value of the descretization interval size actually
leads to exponentially growing solutions. This fact, somewhat, limits the
suitability of CSSL-IV on the Cyber 205 for the simulation of models
characterized by elliptical partial differential equations.
