What is SIMBA?

In the vast realm of astrophysics, understanding molecular abundances is essential for interpreting the cosmos. Enter SIMBA, an innovative Python-based astrochemical modelling package specifically designed to decode chemical reaction networks across various celestial environments.

Why SIMBA Matters

This groundbreaking software employs standardized rate equation methodologies to evolve molecular abundances based on specified physical conditions. SIMBA seamlessly integrates gas-phase chemistry, grain-surface interactions, and photochemical processes, making it a crucial tool in the scientific toolkit.

Performance Meets Accessibility

Crafted with Python for easy access, SIMBA incorporates just-in-time compilation for its performance-critical routines, ensuring computational efficiency ideal for research use. One standout feature is its user-friendly graphical interface, allowing scientists to swiftly explore chemical evolution amidst fluctuating physical conditions.

Dynamic Simulations Made Simple

What sets SIMBA apart? Its ability to complement more demanding multi-dimensional models. For instance, we showcase its prowess by modeling chemical evolution in a photoevaporative flow subjected to intense FUV irradiation. By linking multiple SIMBA instances, we create a dynamic 1D model where gas not only evolves chemically but also reacts dynamically.

Revolutionizing Predictions

This new method reveals astonishing insights: unlike traditional static models—where chemistry in each grid cell operates in isolation—SIMBA demonstrates that certain molecular ices, especially those with robust binding energies like H2O, can endure much deeper into the flow than previously thought.

An Open-Source Odyssey

With endless possibilities for expansion into higher dimensional investigations, SIMBA is openly available to researchers and comes equipped with comprehensive documentation, making it invaluable for those seeking to unravel the complexities of chemical processes in space.
