NOTE: Julia is a Just In Time (JIT) programming language. The first time something is executed it will take longer because of the compilation process. Subsequent calls the the same code will be blazingly fast.
Import the necessary packages
using Plots # for plotting
using FUSE # this will also import IMAS in the current namespaceStarting from a use-case
FUSE comes with some predefined use-cases, some of which are used for regression testing.
Note that some use cases are for non-nuclear experiments and certain Actors like Blankets or BalanceOfPlant will not perform any actions.

- FUSE stores data following the IMAS data schema.
- The root of the data structure is
dd, which stands for "Data Dictionary". - More details are available in the documentation.

⋮Plotting data from dd
FUSE uses Plots.jl recipes for visualizing data from dd.
This allows different plots to be shown when calling plot() on different items in the data structure.
Learn more about Plots.jl here
For example plotting the equilibrium...
plot(dd.equilibrium)
...or the core profiles
plot(dd.core_profiles)
Whant to know what arguments can be passed? use help_plot() function
help_plot(dd.equilibrium; core_profiles_overlay=true, psi_levels_in=21, psi_levels_out=5, show_secondary_separatrix=true, coordinate=:psi_norm)
These plots can be composed by calling plot!() instead of plot()
plot(dd.equilibrium; color=:gray, cx=true)
plot!(dd.build; equilibrium=false, pf_active=false)
plot!(dd.pf_active)
Plotting an array...
plot(dd.core_profiles.profiles_1d[1].pressure_thermal)
...is different from plotting a field from the IDS (which plots the quantity against its coordinate and with units)
plot(dd.core_profiles.profiles_1d[1], :pressure_thermal)
Customizing plot attributes:
plot(dd.core_profiles.profiles_1d[1], :pressure_thermal; label="", linewidth=2, color=:red, labelfontsize=25)
Working with time series
The IMAS data structure supports time-dependent data, and IMAS.jl provides ways to handle time data efficiently.
Each dd has a global_time attribute, and actors operate at such time
dd.global_time0.0Here we see that equilibrium has mulitiple time_slices
dd.equilibrium.time2-element Vector{Float64}:
-Inf
0.0Accessing time-dependent arrays of structures, via integer index
eqt = dd.equilibrium.time_slice[2]
eqt.time0.0At a given time, by passing the time as a floating point number (in seconds)
eqt = dd.equilibrium.time_slice[0.0]
eqt.time0.0At the global time, leaving the square brackets empty
eqt = dd.equilibrium.time_slice[]
eqt.time0.0Using the @ddtime macro to access and modify time-dependent arrays at dd.global_time:
dd.equilibrium.vacuum_toroidal_field.b02-element Vector{Float64}:
7.80034989842101
7.80034989842101Accessing data at dd.global_time
my_b0 = @ddtime(dd.equilibrium.vacuum_toroidal_field.b0)7.80034989842101Writin data at dd.global_time
@ddtime(dd.equilibrium.vacuum_toroidal_field.b0 = my_b0 + 1)
dd.equilibrium.vacuum_toroidal_field.b02-element Vector{Float64}:
7.80034989842101
8.800349898421011Expressions in dd
Some fields in the data dictionary are expressions (ie. Functions). For example dd.core_profiles.profiles_1d[].pressure is dynamically calculated as the product of thermal densities and temperature with addition of fast ions contributions

all:2Whole facility design
Here we restore the :init checkpoint that we had previously stored. Resetting any changes to dd, ini, and act that we did in the meantime.
@checkout :init dd ini actActors in FUSE can be executed by passing two arguments to them: dd and act. Internally, actors can call other actors, creating workflows. For example, the ActorWholeFacility can be used to to get a self-consistent stationary whole facility design. The actors: print statements with their nested output tell us what actors are calling other actors.
FUSE.ActorWholeFacility(dd, act);
nothing #hideLike before we can checkpoint results for later use
@checkin :awf dd ini actRunning a custom workflow
Let's now run a series of actors similar to what ActorWholeFacility does and play around with plotting to get a sense of what each individual actor does.
Let's start again from after the initialization stage
@checkout :init dd ini actLet's start by positioning the PF coils, so that we stand a chance to reproduce the desired plasma shape. This will be important to ensure the stability of the ActorStationaryPlasma that we are going to run next.
actor = FUSE.ActorPFdesign(dd, act);actors: PFdesignThe ActorStationaryPlasma iterates between plasma transport, pedestal, equilibrium and sources to return a self-consistent plasma solution
peq = plot(dd.equilibrium; label="before")
pcp = plot(dd.core_profiles; color=:gray, label="before")
FUSE.ActorStationaryPlasma(dd, act);
nothing #hidewe can compare equilibrium before and after the self-consistency loop
plot!(peq, dd.equilibrium; label="after")
we can compare core_profiles before and after the self-consistency loop
plot!(pcp, dd.core_profiles; label="after")
here are the sources
plot(dd.core_sources)
and the flux-matched transport
plot(dd.core_transport)
HFS sizing actor changes the thickness of the OH and TF layers on the high field side to satisfy current and stresses constraints
plot(dd.build)
FUSE.ActorHFSsizing(dd, act);
plot!(dd.build; cx=false)The stresses on the center stack are stored in the solid_mechanics IDS
plot(dd.solid_mechanics.center_stack.stress)LFS sizing actors change location of the outer TF leg to meet ripple requirements
plot(dd.build)
FUSE.ActorLFSsizing(dd, act);
plot!(dd.build; cx=false)
