Current Continuity in 1D PIC #5331
-
When I run the conditions for Turner's benchmark (https://doi.org/10.1063/1.4775084, but am unable to match power to electrons: My guess is that the root of this problem is that total current is not continuous across the device, as should be the case from the steady state continuity equations: Do you know what is leading to this non-continuous current in WarpX? I have ran Turner's benchmark on another code in the past and did not have issues with current continuity. |

Hi @budjensen. Thanks for bringing this up!
I'm wondering if the time-centering of the currents might play a role here. How are you getting the individual the positions and velocities are known, so to get the velocities should be pushed forward by a half time step. An issue of this type would show smaller error with smaller as you observed and be more noticeable for the electrons since their velocities change more drastically over a single step.
