Any physics. One language.
Open-source computational physics
Eqiora helps researchers and engineers turn mathematical models into simulations, with the physics, numerical choices, and results kept explicit.
Release 0.1.2 · Read the release notes.
From equations to results
Keep the physics in view.
Define the model
Describe quantities, equations, geometry, and boundary conditions. Make the assumptions visible.
Choose the numerics
Select a discretization and solver through a realization, separate from the mathematical model.
Inspect the result
Follow the run into fields, diagnostics, and plots. Trace the result back to the choices that produced it.
One equation, one prediction
Run it. Change it. Understand it.
For dx/dt + kx = 0 with x(0) = 1 and a decay rate of one per second, the model predicts x(1) = exp(-1) ≈ 0.367879. Install Eqiora, run the model, then double the rate and test your next prediction.
Featured walkthrough
