CaNS (Canonical Navier-Stokes) is a high-performance simulator for massively-parallel numerical simulations of fluid flows. It is specifically designed to solve problems involving incompressible, Newtonian fluids, making it a popular choice for researchers and engineers in fluid dynamics. CaNS is widely used in simulations of turbulence, vortex dynamics, and large-scale atmospheric or oceanic flows.
CaNS is currently running version 2.3.4 for CPU, built with OpenMPI 4.1.2 and FFTW 3.3.8 for parallel processing and efficient Fourier transforms. A GPU version is planned for a future release to enhance performance.
Give it a Go: Try CaNS on the Cloud with Inductiva!
Here’s a quick example code to get you started. In this example, we run a CaNS simulation on a c2-standard-4 machine using Inductiva API. Ensure your input files include a ‘data’ folder for storing simulation outputs! To try it out, simply paste the code into your Python environment.
For more details on the simulator’s features and configurations, visit the official CaNS site.

import inductiva
# Allocate Google cloud machine
cloud_machine = inductiva.resources.MachineGroup( \
provider="GCP",
machine_type="c3d-standard-180")
# Initialize the Simulator
cans = inductiva.simulators.CaNS()
# Run simulation with config files in the input directory
task = cans.run( \
input_dir="path/to/my/cans/files",
sim_config_filename="my_config_file.nml",
on=cloud_machine)
# Wait for the simulation to finish and download the results
task.wait()
cloud_machine.terminate()
task.download_outputs()
