Equations🔗
The solver employs the SIMPLE algorithm to solve the continuity equation:
\[\div \u = 0\]and momentum equation:
\[\div ( \u \otimes \u ) - \div \vec{R} = - \grad p + \vec{S}_u\]Where:
- \(\u\)
- Velocity
- \(p\)
- Kinematic pressure
- \(\vec{R}\)
- Stress tensor
- \(\vec{S}_u\)
- Momentum source
