# Main: APM.SEQUENTIAL - APMonitor Option

 Type: Integer, Input
Default Value: 0
Description: Sequential solution method
0=Off
1=On


SEQUENTIAL determines whether a the solution is attempted with a simultaneous (0) or sequential (1) approach. The sequential solution method solves independent decision variables in an outer loop from the system equations. This approach attempts to maintain feasibility from iteration to iteration but can significantly slow down the overall solution time. The SEQUENTIAL option can be used with any problem that has degrees of freedom such as IMODE=2,3,5,6. When IMODE=7-9 (Sequential Dynamic Simulation, Estimation, and Control), the SEQUENTIAL option is automatically elevated to 1 and placed back to the default of 0 when the solution is completed.
