Meeting Update 07/08/2013 - Eddie

Just got back into the swing of things today, so not much to report in terms of results. Here's where I'm at now with my various projects:

Pulsed Jets Paper

The paper is coming along fine. I can only work on the 2.5D parts, since the 3D runs are still blowing up.

3D Jets (precessing)

Implemented a precessing injection velocity and tried running a few simulations. I have low resolution runs for theta = 3 and 1 deg. The precessing period is 1/3 of the pulsation period. The resolution is 24 x 120 x 24 + 1.

I tried a higher resolution (3 levels) on kraken for theta = 2, 1, and 0.1 deg, but they failed to complete. I backed down to 2 levels and am trying the theta = 1 deg run again.

3D Jets (testing minimum temperature)

At the meeting two weeks ago, Jonathan mentioned that some of my simulations had these "flashes" in the temperature plot. We suspected it might be pressure protections, so I tried a run where I increased the minimum temperature. That run completed and the data is on Kraken waiting to be visualized.

3D Jets (fixing the explosions)

We still don't know for sure what caused the explosions, but we've seen some interesting grid effects at the injection boundary. Today and tomorrow, I am going to implement a sub-sampling routine into my problem module. This should be a much more accurate way of initializing radial profiles on a Cartesian grid.

3D Jets (colliding)

We heard back from Sergei and Andrea, and they are going to give me some initial parameters soon that I can use to run some comparable simulations.

1D Radiative Shocks

Just got an email from Pat today. He needs the data in a specific format to make plots, so I will work on reproducing that stuff for him soon.
