Visualizing Your Simulation Results

After running the 400 simulations in Generate the Dataset, it’s time to download and visualize the results.

To simplify the process, we’ve provided a few helper scripts.

Step 1: Download the Simulation Results

Start by downloading the results from the cloud using the following command:

inductiva project download splishsplash_400

This will create a folder named inductiva_output in your current directory, containing the output files from all 400 simulations.

Step 2: Generate Visualizations

To visualize particle movements from each simulation, we’ve created a Python script that processes the results and generates individual GIFs.

Download the visualization script here: 👉 Download splishsplash_gen_viz.py

How to Use the Script

1. Place the downloaded splishsplash_gen_viz.py file in the same directory as the inductiva_output folder.
2. Create a new folder named gifs in the same directory to store the generated visualizations.
3. Run the script with the following command:

python splishsplash_gen_viz.py

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

If any required packages are missing, install them using:

pip install vtk numpy imageio

Once the script finishes, you’ll find a collection of GIFs in the gifs folder — one for each simulation. Each animation captures the motion of particles over time, providing a clear visual representation of the simulation dynamics.

Next, we’ll show you how to combine these individual GIFs into a single animation, making it easier to compare simulation results side by side.
