> The stimulation process using Virtual Lab simulation and the proprietary data archive. The process begins on the left and proceeds clockwise. Solid lines are the process steps and dashed lines are data transfers into, out of, or within the data archive. A real-time feedback loop can update the model while the crew performs the treatment.
