Re: [sparta-users] Segmentation Error Encountered in Simulation

[Woode, B. [U. (DS) <Bry...@ng...>]

Hello All,

I figured out the cause of my segmentation error. It turns out that my initial grid defined by the "create_grid" command was too coarse. After refining my initial grid with "create_grid" my simulation ran just fine. I'm not sure if there's a limit on the number of particles in a cell, but my suspicion is that I had too many particles being emitted (via fix/emit surf command) into a single cell.

Subject: EXT :[sparta-users] Segmentation Error Encountered in Simulation

Hello SPARTA Users,

I am encountering the "segmentation fault" error and have not been able to troubleshoot the issue. From my log file it looks like it crashes when the run begins. For my nrho I am using the maximum number density emitted by my surface, but my background gas has a number density of ~7e16.

Is the problem coming from my nrho and fnum? Any help would be much appreciated.


Respectfully,
