Radiation Dominated Disk:

Zero Net Flux:

The four primary zero net flux simulations are depicted below.

Run 7/13
Location II
Degenerate Grid


Run 7/18
Location I
Degenerate Grid


Run 7/21
Location II
Non-Degenerate Grid


Run 7/24
Location I
Non-Degenerate Grid


Net Flux Simulations:

Each of the following simulations was run at Location II in a Non-Degenerate Box. The initial magnetic field is now aligned parallel to the z axis throughout the box.
In Run 8/03(a), the field's magnitude is the same as in our previous simulations.

Run 8/03(a)
Location II

Reduced Time FFT
Spectra from the Last 30% of the Run


Modified Time FFT
Spectra Using a Sound Speed Scaled Time


The following simulations is identical to Run 8/03(a) excepting that the initial magnetic field strength has been halved.

Run 9/11
Location II

The following simulation was run at Location I using a Non-Degenerate Box. The magnetic field's magnitude is equal to that in Run 7/24 and is directed in the z direction.

Low Radiation Pressure, Net Flux Simulations:

The following simulations initialize with a significantly lower P/p ratios (1.25 and .1 for Locations III and IV, respectively) in a Non-Degenerate Box. The magnetic field is at full strength.
