Each optimization cost, constraint, or sensitivity evaluation results in a complete
simulation.
Simulation results are stored in a directory when a sensitivity analysis is done. The
summary.log file for the four-bar model indicates that 31 sensitivity evaluations
were performed.
First, the initial_run directory is created. This directory contains the
results of a simulation performed with the original model, before any
optimization is attempted.
Next, for each iteration k, a directory iter-k is created as shown in the
figure below. Figure 1. The directory hierarchy from an optimization of the four bar
mechanism
Each directory contains all the output that was generated by MotionSolve. No output is discarded. The option to create some output
files is specified in the MotionSolve input language; their
generation may be optional. Figure 2.
Taking the four-bar example once again, each simulation creates the following
files:
test-4bar.xml, the MotionSolve XML
deck.
test-4bar.log, the MotionSolve log file
for the simulation.
test-4bar.abf, the binary file that can be used for
plotting.
test-4bar.h3d, the binary file that can be used for
animation and graphical results visualization.
test-4bar.mrf, the binary MotionSolve
results file.
