In this talk I will present three tools developed for analysis and visualization of fusion simulations. The first tool, the Poincaré Plot was designed for analyzing the magnetic field topology in MHD simulations. Specifically, our goal was to develop an interactive tool that could quickly construct the major features of the magnetic field while at the same time analyze the topology and identify island chains. To accomplish this task we treat the magnetic fieldline as a signal and search for harmonics in both toroidal and poloidal directions. The second tool is a query based selection tool that allows for the interrogation particle based codes, as such PIC used in gyrokinetic simulations. Searching through millions to billions of particles to find anomalies can be a time consuming process. Our query based tool utilizes index based selection to speed up the search while allowing the user to form range based queries over multiple time steps. The end process allows the user to quickly form "what if" questions and search for correlations in the data such as those found with particles that diffuse radially during the simulation. The last tool forms the basis for constructing and performing synthetic diagnostics for comparing experimental and simulation data. Such tools allow scientists to perform validation comparisons as part of their V&V process. All of the tools have been developed and deployed as part of the VisIt toolkit.
