    The task node is the primary element driving the simulation's outcome. Task nodes simulate system behavior by allowing programmer-specified effects, task duration, failure rates, and pathing. Task Effects are programmer-specified C# expressions where programmers can manipulate variables and data structures when a task is invoked.

    The Sentient World Simulation project (SWS) is to be based on SEAS. The ultimate goal envisioned by Alok R. Chaturvedi on March 10, 2006 was for SWS to be a "continuously running, continually updated mirror model of the real world that can be used to predict and evaluate future events and courses of action.

    en.wikipedia.org/wiki/RELAP5-3D

    RELAP5-3D is an outgrowth of the one-dimensional RELAP5/MOD3 code developed at Idaho National Laboratory (INL) for the U.S. Nuclear Regulatory Commission (NRC). The U.S. Department of Energy (DOE) began sponsoring additional RELAP5 development in the early 1980s to meet its own reactor safety assessment needs.
