This is the new implementation of Dual Energy, following Bryan 2013:

The pressure is computed using the next condition:

The Internal Energy is synchronized using only the next condition:

Comparison: VL and SIMPLE Integrators

Both simulations are using the next Dual Energy parameters:

Row 1: SIMPLE Integrator

Row 2: VL Integrator

Let’s forget about VL integrator.

Cell Difference

Here is the L1 Distance defined for a field as:

NOTE: The scale for each field is different.

Projections

Dual Energy parameters used for Cholla:

Now the projected distance is 25 Mpc/h and the difference ranges from [-1, 1].
