Description
1 - Nature of physical problem solved: EXPANDA-70 is a one-dimensional, real or adjoint solution for a slab, cylinder or sphere, and at the same time a dimensional critical search may be made, if requested. In the numerical solution, the methods are the same as EXPANDA-4. Therefore, EXPANDA-70 is an extension of EXPANDA-4. 2 - Method of solution: The central difference approximation is adopted for the differential coefficients. The three points difference equation is solved by the ordinary sets of two points recurrence formula
