+Total energy v time plots were made in Visit using a cylinder clip operator and the query summing function,

+[[Image()]]
+
+We varied the size of the 'collision region' we were integrating through to account for the shear angle, 
+
+|| [[latex($\theta$)]] || Lx || Ly = Lz ||
+|| 0 || 20 pc || 40 pc ||
+|| 15 || NA || NA ||
+|| 30 || NA || NA ||
+|| 60 || NA || NA ||
+
+The expressions in Visit were:
+
+|| Kinetic Energy || .5*rho(vx^2^+vy^2^+vz^2^) ||
+|| Magnetic Energy || .5(B^2^) ||
+|| Gravitational Energy || gas phi*rho  ||
+
+The gravitational energy computed this way neglects particle-gas interactions, and so is an approximation to the total gravitational energy of the collision region.

 Below are a series of simple line plots for particular energies over time in our colliding flows runs (all beta = 0, for varying shear angles (0 (No Shear), 15, 30, and 60). The energies we are plotting are defined below. The independent variable on these plots is the time in Myr for the ratio of the energy at a particular time over the initial energy at t = 0 Myr. Hence we see that each plot is normalized at 1 on the dependent axis. Here I will describe the process of how we acquired these plots.
