   - Having succesfully performed the above two steps, we replced the steady cloud of gas with a source generating ​ outgoing mass flow which basically represents 1d version of the solar wind. For the same, we introduced a velocity of 5 at the center in two oppisite directions and a density of 2.  ​   - Having succesfully performed the above two steps, we replced the steady cloud of gas with a source generating ​ outgoing mass flow which basically represents 1d version of the solar wind.

   - Myself and Raditya, figured out the input parameters for the problem using Brian Field'​s paper on "​Supernova Collisions with the Heliosphere"​. We tested those parameters on the 1D set-up for the problem, basically we replaced the random numbers we used on 06/02 with real numbers describing the problem in 1D format.   - Myself and Raditya, figured out the input parameters for the problem using Brian Field'​s paper on "​Supernova Collisions with the Heliosphere"​.

   - The resulting density, pressure and velocity plots in 1D looked reasonably good. So we gave those parameters to Alex to be used into the 2D code.   - The resulting density, pressure and velocity plots in 1D looked reasonably good.

   - Changed the 2D inputs to more natural units ([L]=1 AU, [T]=1 yr, [M]=10^12 g) because VH-1 would crash when using the cgs system for our problem.   - Changed the 2D inputs to more natural units ([L]=1 AU, [T]=1 yr, [M]=10^12 g) because VH-1 would crash when using the cgs system for our problem.

   - Finally running a realistic simulation of the collision, now we are all set for producing a high-res video and a low-res parameter study tomorrow.   - Finally running a realistic simulation of the collision, now we are all set for producing a high-res video and a low-res parameter study tomorrow.

 +  - Finalized our input parameters
 +  - Generated high-res simulations (10x4 AU, 750x250 gridpoints) for the presentation
 +  - Did a parameter study on a reduced grid (6x2 AU, 300x100 gridpoints) to determine the dependence of the penetration radius on the densities of the SNR and solar wind.
 +  - Figured out how to create animated gifs / videos of the NetCDF files using [[https://​wci.llnl.gov/​codes/​visit/​|VisIt]]
 +  - Created our presentation
