The authors have constructed a relatively simple, customized Python module that plugs smoothly into an otherwise standard workflow within VisTrails. This has resulted in the capability to quantitatively analyze complex fluid flows in simulations of merging binary stars. The resulting visualization tool permits researchers to identify values of key rotational frequencies associated with such flows and how these frequencies change over time.
