Simulations using Hybrid-PIC model #5975
-
|
Hi all, I am starting to use the warpx and would like to simulate long time scale (10's of nano seconds) laser interaction with under dense plasmas using the Kinetic-fluid Hybrid Model. Basically I wanted to simulate the laser propagation with plasma hydrodynamics. What I understand from the documentation is that since the Kinetic-fluid Hybrid Model uses Ohm's law and assumes that the electrons are inertialess ( hence no time derivatives involved ) for electric field calculation, I cannot use it for time varying fields but only constant fields. |

Hi @Ramtron108. Welcome to the WarpX community! The Ohm's law implementation neglects displacement current and consequently it does not include light waves. But if you are interested in 10's of nano-seconds, that timescale should be accessible with fully kinetic simulations like in the laser plasma acceleration examples (see https://github.com/BLAST-WarpX/warpx/tree/development/Examples/Physics_applications/laser_acceleration). |
