Incompressible Navier-Stokes (INS) equations are a model for incompressible flows:

Chombo simulates incompressible flows using projection algorithms, which enforces the divergence-free constraint with the solution to an elliptic equation based on a Hodge Decomposition:

This flexible approach has been extended to a number of other regimes, including Low-mach number and All-speed asymptotics of Compressible Navier Stokes with embedded boundaries..


There are 3 software libraries that support INS:

In addition, we are currently working on a 4th-order accurate AMR INS solver on rectangular domains. For more details see the Current Research page.
