Jhuighuy / StormRuler

A very high order FVM framework

StormRuler is a FVM-based multidimensional partial differential equations solving framework, written in C++23.

🌀 Equations solved

StormRuler can be used to solve various partial differential equations, including:

• 🌊 Incompressible Navier-Stokes equations,
• 🌪 (planned) Сompressible Navier-Stokes/Euler equations,
• 💧 (planned) Cahn-Hilliard equation,
• ... To be written...
