Nonlinear System Solution with Sparse Matrices

Classes for Nonlinear System Solution with Sparse Matrices 

Problems involving nonlinear systems with sparse structured or nonstructured matrices are commonplace in chemical and process engineering. 

The classes used to solve nonlinear systems with sparse matrices are 

The BzzNonLinearSystemSparse class has several constructors that allow sparse systems of different kinds to be solved. 

The objects in these classes can use certain special functions

For each elementary volume, then, four equations like (9) plus the three equations (10),(11) and (12) are written. The reac tor zones can be separately computed in sequence for each, 7N nonlinear algebraic equations are to be simultaneously solved. This is performed with the aid of a general program for the solution of large, sparse matrix, nonlinear equations systems, already employed (12) for the simulation of the LDPE vessel reactor. More details on the program are given elsewhere (13).
