First Light Fusion has developed two fluid codes: Hytrac, a 2D Eulerian code with AMR and front-tracking and B, a 3D MHD code with volume of fluid interface tracking. Both codes included subcycled thermal conduction, FEOS equations of state and Lee-More transport.


Hytrac

• Architecture uses two grids: Eulerian grid on which the hydrodynamics equations are solved and a Lagrangian grid tracking fluid interfaces.

• Eulerian grid includes AMR, allowing simulations over a range of scales

• Grid update through exact or approximate Riemann solvers.

B

• 3D resistive MHD code, MHD equations subcycled within hydro solve.

• Volume of fluid method is cheap and simple, allowing arbitrary number of materials with some diffusion at interfaces.
