OSTI ID:7333536
A preliminary version of documentation for the GEARBI package is presented. This package solves systems of ordinary differential equations (initial value problem), with emphasis on stiff systems, in which the Jacobian matrix has a regular block structure. The package takes advantage of that structure and uses a block-iterative (block-SOR) method to solve the linear algebraic systems that arise. In all other respects, GEARBI is much the same as the GEAR package. (UCID-30001, Rev. 3). An earlier version of GEARBI was used for atmospheric kinetics-transport problems in one and two dimensions.
