[aspect-devel] Using tracers on user-specified domains

[FELIPE ORELLANA ROVIROSA]

 Hi all,

       I am trying to implement tracers for visualization of flow
advection, on a 3D convecting system.

      I am willing to use the 'ascii file' option, but I don't find
relevant examples regarding their implementation on the parameter file.
       I have already generated my own file 'tracer_3d.dat' that contains
coordinates of the points I want to be trace-advected. It is a 3 columns
long list, containing 3 float numbers on each row; as simple as that.

      I don't know where to put that 'simple text file' in order for Aspect
to recognize it.

      I tried on the same directory where I have the .prm, and it didn't
work. The error was that Aspect could not locate it under
'data/particle/generator/ascii/tracer.dat>.'

    then I put it right there, in that directory
'data/particle/generator/ascii/, (of course I changed the name of the
preexisting test/example file avoiding to kill it); and it failed:

   Could not open file
</root/SEISMO/usr-local-src/aspect/aspect-1.5.0/data/particle/generator/ascii/tracer.dat>

   The manual 1.5 does not have much info on this, or I have not found it.

 I tried giving the file different names..
     Could not open file
</root/SEISMO/usr-local-src/aspect/aspect-1.5.0/data/particle/generator/ascii/tracer.dat>.

 Where should I put the file? what name should I give it?

cheers^3,
Felipe
