Stop a simulation running in a Jupyter notebook

[mcgoldba]

I have a simulation started with PyFluent in a Jupyter notebook, and want to stop the simulation without loosing the data. How can I do this?

Maybe this is not exactly what you asked for, but here is a solution that worked for me.

I use a while loop combined with a report_interval. The simulation runs for a specified number of iterations, and after each interval, I check if a specific convergence criterion is met. If it is, the loop exits and the simulation stops. Here's an example:

# Initialize iteration parameters
iteration_count = 0
max_iterations = 1000  # Maximum number of iterations
report_interval = 100  # Interval after which to check convergence

# Function to check if the simulation has converged
def has_converged():
    # Implement your specific convergence condition here
    # Return True if convergence criteria are met
    if (...):  # Replace with your actual condition
        return True
    return False

# Main simulation loop
running = True
while running:
    # Run simulation for a specified interval
    solver.run(iteration_count=report_interval)
    iteration_count += report_interval  # Update iteration count

    # Check for convergence after the interval
    if has_converged():
        print(f"Convergence achieved after {iteration_count} iterations.")
        break  # Exit loop if convergence is reached

    # Stop if maximum iterations are reached
    if iteration_count >= max_iterations:
        print("Maximum number of iterations reached. Stopping simulation.")
        break
