Hierarchical Trees of Unsteady Simulation Datasets

We have designed and implemented concept of hierarchical structures consisting of simulation results stored in unsteady (time-varying) datasets. It allows incremental, progressive and easy construction and replaying of various simulation configurations with interactive visualization of results. The ability of modification of simulation boundary conditions is available in every node of the datasets tree. Every interactively selected path in the tree corresponds to one modified simulation solution. We have originally proposed and tested this concept in combustion processes simulation powered by a simple fluid simulator, but it can be easily utilized in general simulation applications, which use unsteady datasets for results storage and replaying.
