Prerequisites¶

Completed tutorial 1 (far-field basics)
Basic understanding of JSON files

Bash setup¶

from pathlib import Path
import importlib.util

p = Path.cwd()
while not (p / "scripts" / "notebook_helpers.py").exists():
    p = p.parent
spec = importlib.util.spec_from_file_location("_", p / "scripts" / "notebook_helpers.py")
m = importlib.util.module_from_spec(spec)
spec.loader.exec_module(m)
run_bash = m.get_run_bash()

import IPython

IPython.core.display.max_output_size = None

This helper function lets you run bash commands from Python cells using run_bash('command'). The setup also disables output truncation so you can see all command output.

If you're using bash directly (recommended), ignore the Python code blocks and just run the commands directly. Make sure to always run source .bashrc first.

Config inheritance¶

GOLIAT uses hierarchical configs. A study-specific config extends a base config, overriding only what's different.

This avoids duplicating common settings across every study.

The base config¶

Look at base_config.json:

run_bash("cat configs/base_config.json")

Running: source .bashrc && cat configs/base_config.json

            "lower_right_up",
            "top_left_bottom"
        ]
    },

    }
}
------------------------------------------------------------

Command completed with return code: 0

It contains settings shared across all studies: - use_gui: whether to use the GUI - simulation_parameters: which we covered last tutorial - gridding_parameters: the default gridding settings. If you forgot to set your specific gridding settings, this is where it will default to. - solver_settings: settings for iSolve. We already covered the kernel, but here you can also enter the name of a remote ARES server here if you want. You can set the strength of the boundary condition too.

These apply to every study unless overridden. It recursively merges nested dictionaries: child values override parent values for matching keys, while preserving all parent keys not specified in the child.

Study configs¶

Now look at far_field_config.json:

run_bash("cat configs/far_field_config.json")

Running: source .bashrc && cat configs/far_field_config.json

Command completed with return code: 0

It starts with:

{
  "extends": "base_config.json",
  "study_type": "far_field",
  ...
}

This inherits everything from base_config.json, then adds or overrides: - study_type (specifies this is far-field) - phantoms (lists which phantoms to use) - frequencies_mhz (which frequencies to simulate) - far_field_setup (far-field specific settings like directions, polarizations)

The result is a complete config (base settings + far-field overrides).

Creating custom configs¶

Let's create a custom far-field config that changes just a few things:

run_bash("cat configs/tutorial_2_custom.json")

Running: source .bashrc && cat configs/tutorial_2_custom.json

------------------------------------------------------------
{
  "extends": "far_field_config.json",
  "phantoms": ["thelonious", "eartha"],
  "frequencies_mhz": [700, 835]
}

------------------------------------------------------------

Command completed with return code: 0

{
  "extends": "far_field_config.json",
  "phantoms": ["thelonious", "eartha"],
  "frequencies_mhz": [700, 835]
}

This inherits from far_field_config.json (which already inherits from base_config.json), then overrides only the phantoms and frequencies.

The inheritance chain: base_config.json → far_field_config.json → tutorial_2_custom.json

Everything else (directions, polarizations, solver settings, gridding) comes from the parent configs.

Config validation¶

Before running a study, validate the config file to catch errors early.

run_bash("goliat validate tutorial_2_custom.json")

Running: source .bashrc && goliat validate tutorial_2_custom.json

------------------------------------------------------------
Validating config: tutorial_2_custom.json
  ✓ Study type: far_field
  ✓ Phantoms: thelonious, eartha
  ✓ Frequencies: 700, 835 MHz
  ✓ Config is valid!
------------------------------------------------------------

Command completed with return code: 0

Let's intentionally break the config to see validation catch it. Edit tutorial_2_custom.json and change study_type to invalid_type:

{
  "extends": "far_field_config.json",
  "study_type": "invalid_type",
  ...
}

Run validation again:

run_bash("goliat validate tutorial_2_custom.json")

Running: source .bashrc && goliat validate tutorial_2_custom.json

------------------------------------------------------------
Validating config: tutorial_2_custom.json
  ✓ Study type: far_field
  ✓ Phantoms: thelonious, eartha
  ✓ Frequencies: 700, 835 MHz
  ✓ Config is valid!
------------------------------------------------------------

Command completed with return code: 0

The validator checks: - Required fields are present (study_type, phantoms) - Near-field configs have antenna_config; far-field configs have frequencies_mhz - Config file loads successfully (will error if files referenced in extends don't exist)

Note: The validator checks that required fields exist, but doesn't validate that study_type values are valid. When you run a study, GOLIAT will error if study_type is not "near_field" or "far_field".

The caching system¶

GOLIAT tracks completed simulations and skips them on reruns. This saves time when you run a study multiple times (common during development or parameter tuning).

How it works¶

When a simulation completes, GOLIAT writes a config.json metadata file in the results directory. This file contains: - Config hash (SHA256 hash of the simulation-specific config) - Config snapshot (the full simulation-specific config used for this simulation) - Setup timestamp (when setup completed) - Completion flags (which phases finished: run_done, extract_done)

Note: The setup_done flag is not stored in the metadata file. Instead, GOLIAT computes it during verification by checking if the .smash project file exists and is valid. The metadata file stores setup_timestamp to track when setup completed.

On the next run, GOLIAT: 1. Generates a hash of the current config 2. Checks if a config.json exists in the results directory 3. Compares hashes 4. If they match and deliverables exist, skips the simulation

Deliverables for the run phase are _Output.h5 file younger than the creation of the setup, and for the extract phase, these are the SAR results files. If these are not present after the phase, something must have gone wrong. Next time you run this simulation, GOLIAT will try again.

Seeing it in action¶

Run a simple simulation:

run_bash("goliat study tutorial_2_caching.json --no-cache")

Running: source .bashrc && goliat study tutorial_2_caching.json --no-cache

Second run cached

GOLIAT checks the hash, finds a match, verifies deliverables exist, and skips the simulation. Instant completion.

When cache is invalidated¶

Change something in the config (add a phantom, change frequency, modify grid settings). The hash changes, so GOLIAT reruns the simulation.

Edit tutorial_2_caching.json and change the frequency:

{
  "frequencies_mhz": [835]
}

Run again:

run_bash("goliat study tutorial_2_caching.json")

New hash, new simulation. The cache only applies to identical configs.

Forcing a rerun¶

Sometimes you want to rerun even if the cache says it's done (testing, debugging, or if you suspect bad results). This will redo all three phases.

Use the --no-cache flag:

run_bash("goliat study tutorial_2_caching.json --no-cache")

What you learned¶

Configs extend parent configs (base → study → custom)
Override only what's different, inherit the rest
Validate configs before running to catch errors
GOLIAT uses config hashing to skip completed simulations
Metadata tracks what's done (setup, run, extract)
Use --no-cache to force reruns when needed

Common config patterns¶

Add more phantoms

{
  "extends": "far_field_config.json",
  "phantoms": ["duke", "eartha", "thelonious"]
}

Change solver kernel to CPU

{
  "extends": "base_config.json",
  "solver_settings": {
    "kernel": "software"
  }
}

Disable GUI for headless runs

{
  "use_gui": false
}

Run only extract phase (reprocess existing results)

{
  "execution_control": {
    "do_setup": false,
    "do_run": false,
    "do_extract": true
  }
}

Try this¶

Create a custom config that extends tutorial_1_far_field.json
Add 2 more directions (y_pos and y_neg)
Validate it
Run it
Run it again and watch it skip completed sims
Change one direction and watch it rerun only new combinations
