[CIG-MC] Segmentation fault error when adding tracers

[tan2]

Hi Scott,

The 2nd dimension in your coor.dat is wrong.

nsd= 2
1    3.2376
2    3.2368
3    3.2359
 .
 .
64    3.1860
65    3.1852

The coordinate must be an increasing function.

Besides this problem, there is another possible obstacle in your setup.
Enabling low viscosity channel will create some passive (weightless)
tracers. Enabling chemistry will create active tracers. The code cannot
handle both types (passive and active) of tracers correctly when both are
present.


Eh
