| - 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. | ||
| + | - Fixed an error in our input densities. | ||
| + | - Fixed the bug of density accumulating on the symmetry axis (we use cylindrical coordinates) by setting the density of the two innermost gridpoints in each column to the value of the third. This is a quick and dirty fix and unphysical! However, we think the problem is caused by some boundary condition/ghost zone issue that we were not able to resolve after spending several hours on it. We thank Richard for suggesting this fix! | ||
| + | - 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. | ||
