Cosmological Evolution Archetypes

Goal: Simulation of the Universe from a period just after the big bang to now. To decide if current theories of large scale structure formation match the observed universe. There are three classes of archtetypes:

• Initial Conditions. To compute the initial conditions of the expansion phase of the evolution just after the big bang.
• Fluid Flow Models. Simulate the flow of matter as a fluid subject to gravetational forces.
• Particle Based Methods. Simulate the evolution as a large number of particles (galexies) subject to gravitational forces.

Fluid Flow Modeling

• Algorithms. (this archetype is a special subclass of the 3D compressible flow CFD archtetype.)
• Visualization Results. Movie of Gas Density Evolution by Bryan and Norman in a Cold + Hot Dark Matter Universe. (More visualizations here.

Particle Base Methods

• Particle Mesh Methods.
• Self-Consistent Field Method.
• Tree Methods.
• Hybrid Schemes.
