Test Your Inductiva Setup

Before diving into tutorials and benchmarks, let's ensure that your Inductiva Python package is properly set up. To confirm everything is working as expected, simply run a quick WAVEWATCH III simulation — it only takes a minute!

Step 1: Copy and Run the Code

1. Copy the code below and save it as example.py on your Desktop (or in your preferred directory).

"""WAVEWATCH III example."""
import inductiva

# Allocate cloud machine on Google Cloud Platform
cloud_machine = inductiva.resources.MachineGroup( \
    provider="GCP",
    machine_type="c2d-highcpu-4",
    spot=True)

# Download the input files into a folder
input_dir = inductiva.utils.download_from_url(
    "https://storage.googleapis.com/inductiva-api-demo-files/"
    "wavewatch3-input-example.zip",
    unzip=True)

# Initialize the Simulator
wavewatch3 = inductiva.simulators.WaveWatch3(
     version="11-2024")

# List of commands to run
commands = ["ww3_grid", "ww3_prep", "ww3_shel"]

# Run simulation
task = wavewatch3.run(
    input_dir=input_dir,
    custom_switch="switch_PR3_UQ_MPI",
    commands=commands,
    on=cloud_machine)

# Wait for the simulation to finish and download the results
task.wait()
cloud_machine.terminate()

task.download_outputs()

task.print_summary()

2. Open your command line, then navigate to the Desktop by running:

cd ~/Desktop

3. Execute the Python script by running:

python example.py

Note: On some systems, you might need to use python3 instead of python.

All the necessary simulation artifacts and configuration files will be automatically downloaded to your computer. The WAVEWATCH III simulation will then be sent to a cloud machine for execution.

Step 2: Verify the Task Status

After the simulation completes, a task summary will be displayed in your terminal, as shown below.

Task status: Success

If the task status shows Success, congratulations! You've successfully run an WAVEWATCH III simulation.

This simple example tested your installation on a small machine with just 4 virtual CPUs. Inductiva offers far more powerful options to supercharge your simulations.
