​Notes

Run time on Stampede2

Frame rate for the jet modal on 120 cores:

First 20 frames 2.3 hr/frame
Frame 21-30 1.5 hr/frame
Later 1 ~ 1.2 hr/frame

Time for one modal with 120 framesis ~170 hours in wall time = 20 400 SUs.

I have 3 runs planned for this week, which will use about 81 200 SUs.

PN talk for EAS2020

Presentation time is 15 min, including a 4-5 min Q&A and 1 min for transition. I will prepare 10 slides max for the talk, and maybe <2 extra slides for questions.

Outline:

  1. Introduction to the problem. Show ~2 examples of bipolar PPN with collimated jets.

  1. Simulation setup (1): initial condition from the SPH model, choice of physical parameters.

  1. Simulation setup (2): technical details in the AMR simulations: relax the ejecta on AMR grid, fallback during the quiescent period, regions of refinement, and application of the cooling curve.

  1. Results (1) - model A, the central pillar of jets and inner shock

  1. GISW model and the elliptical shock

  1. Results (2) - model B and model C

  1. Results (3) - model D, compare to OH 231.8+04.2

  1. Asymmetries in line plots

  1. Momentum budget

  1. Conclusions

Meeting on rad hydro

Thursday (6/18) at 11 am. Zoom coordinates to be emailed.
