v30 v31 47 47 == 3D Runs == 48 48 49 === Simulation Setup ===49 === Simulation Setups === 50 50 All simulations are done in a reference frame moving at M = 7. Simulation times are shown in computation units, but the total physical time is approximately 75 years. 51 51 … … 54 54 3-clump setup (runs G - L): See diagram below. The clumps are labeled by their Mach numbers. The clump separation d (measured in clump radii) and angle a are the defining parameters that change for each run. The point labeled '''O''' marks the observer. The position of the observer is determined by two angles: the rotation angle phi is denoted in the diagram, and the inclination angle i cannot be shown in a top view diagram, but it is simply the angle at which the flow is directed towards the observer (0 deg is perpendicular and 90 is directly at the observer). 55 55 56 [[Image(3clumpsetup.png,width= 400)]]56 [[Image(3clumpsetup.png,width=250)]] 57 57 58 58 multi-clump setup (run M): In x and z, the clumps are arranged in a 3-4-3 lattice-like structure. Each clump is given a random position in y and an appropriate velocity based on that y-position so that the clump does not run off the grid during the simulation.
