<p>PROBLEM TO BE SOLVED: To enable convergence without taking relieving actions accompanying difficult works regarding multivariables for assuring the convergence in the case of repeatedly calculating nonlinear multivariable problems to appear when a time developing simultaneous partial differential equation for expressing a nonlinear physical phenomenon is solved by calculation. SOLUTION: This solution calculator of the nonlinear multivariable problems sets sensitivity matrixes to be problems, parameters and an initial value for solving the sensitivity matrixes, solves a sensitivity equation by calculating the sensitivity matrixes, repeatedly calculating the sensitivity matrixes by updating solutions and variables, decides the convergence of calculation to be performed by a repeated calculation part, calculates a degree of nonlinearlity by using two optional different sensitivity matrixes to be used in repeated calculation in the repeated calculation part and solves the sensitivity equation corrected according to a convergence decision result by the deciding part and the degree of nonlinearlity calculated by a degree of nonlinearlity calculating part.</p> |
