Overview This is a step through of the VL+CT (Van Leer plus Constrained Transport) integrator I’m going to add to my hydro-sandbox code. The specific algorithm is from Stone & Gardiner 2009 wh...

General Relativity (GR) We started on Black Holes this week and had a midterm exam. It went well but studying for it took a lot of time. HLLD Solver As of last week I finished writing the HLLD sol...

General Relativity (GR) Working on Schwartzchild solution to Einsteins field equation and how to work with Schwartzchild coordinate and metric. GR this week took most of Monday and all of Thursday....

General Relativity (GR) Discussed the Alcubierre metric/warp drive and more digging into curved spacetime. HLLD Solver Building on the work from last week I finished up the prep work for the HLLD ...

General Relativity (GR) Nothing too exciting. Starting hard into curved spacetime. Dotfiles Presentation On Wednesday I gave a presentation on how I organize dotfiles to the computational astrophy...

General Relativity (GR) We had an exam Monday and started into GR on Wednesday. Pretty uneventful. Intel Workshop On Tuesday I went to the Intel Dev Tools workshop hosted at the Pitt CRC. It had a...

Overview This is a step through of the HLLD Riemann solver I’m going to add to my hydro-sandbox code. The specific algorithm is from Miyoshi & Kusano 2005 which is the original paper where the...

General Relativity (GR) In class we’re covering Newtonian curved spacetime. I spent Monday on the homework and we have an exam next Monday so that’s what I will be studying for the rest of the week...

General Relativity (GR) Moving from special relativity to general relativity this week. The homework was pretty long so I spent two days on that. HLLC Riemann Solvers I’m about half done writing a...

Overview This is a step through of the particular HLLC Riemann solver I’m going to add to my hydro-sandbox code. It will serve as a base and teaching tool for my future implementation of an HLLD M...
