FORSIM: a FORTRAN-oriented simulation package for the automated solution of partial and ordinary differential equation systems
Technical Report

OSTI ID:4937335
The FORSIM program is a versatile general package for the solution of partial and/or ordinary differential equation systems. The program has been in use as an ordinary differential equstion package for some time, both at Atomic Energy of Canada Limited and at several other institutions and an adequate user's manual (AECL-431l) already exists for this application. The program is now extended to provide automstic solution of a variety of linear and nonlinear partial differential equations. The partial differential equations are converted into a set of coupled ordinary differential equations, which are then integrated in time using an error controlled variable step integration algorithm. The equations, initial conditions and any special instructions are specified by the user in a single FORTRAN subroutine. This is then loaded with the control routines which perform the solution and any necessary input or output. A description of the application of the FORSIM system to partial differential equations, instructions for its use, and several illustrative examples are given. A more detailed description of the philosophy and content of the FORSIM system has been given in Atomic Energy of Canada Limited report AECL4311. (auth)
