Pressure Based Load Balancing

 

Each green dot represent a computational cell and each red Voronoi cell represents a CPU domain. The load balance is defined as the maximum number of computational cells in a domain over the ideal number. For more details see.

G2 Gas Cloud

This is a movie showing the density of the G2 gas cloud using ideal gas EOS and cooling tables taking from CLOUDY. As the cloud passes through pericenter, it is shock heated and then undergoes a cooling instability that fragments it.

This is a movie showing the density of the G2 gas cloud using ideal gas EOS and cooling tables taking from CLOUDY. The simulation is only of the pericenter passage and simulates the vertical and radial axes. At the end of the run, the cloud is fragmented due to cooling instabilities.

This is a movie showing the density of the G2 gas cloud using ideal gas EOS and cooling tables taking from CLOUDY. Here the ambient medium is diluted by a factor  of 20 and as a consequence it does not undergo a cooling instability that fragments it.
