Running a 2³ simulation of the colliding flows module with all the physics I will be using turned on, to get an idea of the baseline memory usage for this module.

I extended the time out to t=1000 so get a longer time on the processors. On bamboo, I run the job on 8 processors and give the command top. The virt column shows the memory usage to be 186 mb per process.

To test the difference in memory usage with the different physics on/off, compiled astrobear with and without hypre. This is the only expected multiphysics to produce a change in memory usage, as it uses external libraries.
