12Outline of ProgressImproving and substantiating the ARIES Systems Code (ASC)Documentation and ASC homepageStrawmen points issuedVASST GUI for visualizing data

23ASC Flow of Calculations(medium detail)Systems code consists of modular building blocks

Two modes of operation

Adjustable input files

34Power Flow Diagram Ensures Power Accountability

5Power Flow Diagram (zoomed-in)

6 Power Balance Verified

7Generic radial build implementedGeneric radial build allows true modularity of blankets to add components as required.Items not in use are given a thickness = 0.
