Interactive Scenario Builder (Builder) is a modeling and simulation, three-dimensional application developed by the Advanced Tactical Environmental Simulation Team (ATEST) at the Naval Research Laboratory (NRL) that aids in understanding radio frequency (RF) and electro-optical/infrared (EO/IR) propagation.
List of free analog and digital electronic circuit simulators, available for Windows, macOS, Linux, and comparing against UC Berkeley SPICE.The following table is split into two groups based on whether it has a graphical visual interface or not.
VisSim - system simulation and optional C-code generation of electrical, process, control, bio-medical, mechanical and UML State chart systems. Vortex (software) - a complete simulation platform featuring a realtime physics engine for rigid body dynamics, an image generator, desktop tools (Editor and Player) and more. Also available as Vortex ...
The laboratory contains a complete avionics mock-up of a Shuttle, designated OV-095. While only a skeleton of an orbiter, the electronics are identical in position and type to those used on the Shuttle; it is a sufficiently faithful replica that crews sometimes prefer to use it to train on, rather than the training simulators.
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.
2.4 GHz helical antenna radiation pattern (NEC simulation) The Numerical Electromagnetics Code , or NEC , is a popular antenna modeling computer program for wire and surface antennas . It was originally written in FORTRAN during the 1970s by Gerald Burke and Andrew Poggio of the Lawrence Livermore National Laboratory .
PhET Interactive Simulations is part of the University of Colorado Boulder which is a member of the Association of American Universities. [10] The team changes over time and has about 16 members consisting of professors, post-doctoral students, researchers, education specialists, software engineers (sometimes contractors), educators, and administrative assistants.

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.
