************************* initial guess options*************************1 = linear guess with tangential thrusting2 = numerical integration with Edelbaum steering3 = binary data file---------------------2If the user elects to use a binary data file (option 3 above) for the initial guess, the following text inputspecifies the name of the file to use.name of binary initial guess data fileleo2geo_jk.rsbinThe following input can be used to create or update an initial guess binary file. The creation or updateprocess uses the filename defined above. For initial guess option 1, the software will create a binaryrestart file. For initial guess option 3, an input of yes to this item will update the binary file used toinitialize the simulation.******************************* binary restart file option *******************************create/update binary data file (yes or no)noThis next input specifies the type of comma-delimited or comma-separated-variable (CSV) solution datafile to create. Option 1 will create a solution file at each collocation point or node determined by theSparse Optimization Suite software. Options 2 <strong>and</strong> 3 allow the user to specify either the number ofnodes or time step size of the data file.*********************************************** type of comma-delimited solution data file ***********************************************1 = OCS-defined nodes2 = user-defined nodes3 = user-defined step size---------------------------1For options 2 or 3, this next input defines either the number of data points or the time step size of thedata output in the solution file.number of user-defined nodes or print step size in solution data file50The name of the solution data file is defined in this next line. Please consult Appendix A for adescription of the information written to this file.name of solution output fileleo2geo_jk.csvThe next series of program inputs are algorithm control options <strong>and</strong> parameters for the SparseOptimization Suite. The first input is an integer that specifies the type of collocation method to useduring the solution process.********************************* algorithm control parameters *********************************page 5
