Abstract
A program generating method for generating a FORTRAN program by use of a computer having the following steps of automatically selecting an optimal weight function for each equation of the system of partial differential equations including coupled plural variables and partial differential equations to effect a multiplication therebetween, performing a partial integration thereon, automatically selecting from a group of boundary conditions an optimal boundary condition for each partial differential equation to conduct a collation processing of the boundary condition, exchanging the order of the summation and the integration on the object variable to effect a discretize processing of the variable, assigning components to a coefficient matrix and a constant vector, and generating a FORTRAN program to solve the equations through a linear computation.
