Re: [sparta-users] [EXTERNAL] ERROR: Stats fix does not compute vector

[Moore, S. <st...@sa...>]

What are you wanting to achieve? You are trying to output a per-grid quantity from "fix ave/grid" to the stats output which isn't allowed. You can dump per-grid quantities to a file instead, or output the value from one grid cell, but you cannot output the entire grid to stats. See https://sparta.github.io/doc/stats_style.html for more info.

Hello everyone,

I'm trying to run this simulation and get f_1[2] numerical output in log file but i get the "ERROR: Stats fix does not compute vector (../stats.cpp:702)" error. How can i fix this?
