| + | - 1d version of steady cloud of gas created using the following parameters: | ||
| + | * Pressure : pcloud = 1 | ||
| + | * Density : rcloud = 1 | ||
| + | * Velocity : ucloud = 0 | ||
| + | * Ambient density : ramb = 1e-04 | ||
| + | - Then we created a 1d shock wave and let it hit the cloud using the following parameters: | ||
| + | * Pressure : pshock = 10000 | ||
| + | * Density : rshock = 0.5 | ||
| + | * Velocity : vshock = 0 | ||
| + | - 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. | ||
| + | - Finally we ended the day with hitting the schock wave onto the solar wind to see the interaction beteen the two. | ||

| + | - All 3 of us installed netcdf and got the Serial version of VH1 running. Alex worked on setting up the 2D code for the solar wind and the supernova shock. | ||
| + | - 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. | ||
| + | - 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. | ||
