Re: [sparta-users] [EXTERNAL] Spatially dependent surface temperature for surf_collide

[Steve P. <sj...@gm...>]

The input script Stan pointed to allows a static temperature to be defined
for each surf element by
including the values in the read_surf file and assigning them to a custom
per-surf vector.
The custom vector is the temperature argument to the surf_collide command.

If you want a spatially-dependent function to set the temperature
(statically or time-dependent), you
can use a surf-style variable as the temperature arg to the surf_collide
command.  Surf-style variables
can include the center point of each surf in their formula (or the current
timestep).
See the examples/custom/in.custom.step.temp.variable script for an example.
Also see the surf_collided temp/freq keyword to set how often the
surf-style variable is invoked.
The formula could also include outputs from per-surf computes, e.g. to vary
the temperature depending
on the energy flux of particles to each surface element.
