# Cosmological Simulations

For all the tests the box is a 50 Mpc/h box on a $256^3$ cells grid.

## Dark Matter Only

First the comparison against Nyx, both Nyx and Cholla use the second order stencil for the gradient of the potential

Now the comparison against Ramses, both Ramses and Cholla use the fourth order stencial for the gradient of the potential.

Now the comparison against Enzo, both Enzo and Cholla use the fourth order stencial for the gradient of the potential.

Comparison against Enzo using $eta==0.005$ for Dual Energy
Comparison against Enzo using $eta==0.035$ for Dual Energy
