Flow solver flowcharts
This section consists of flowcharts that illustrate the methodology of the flow solver when you run a simple steady-state or transient simulation, and does not cover all features and situations. It also highlights how the flow solver is coupled to the thermal solver for a simple steady-state or transient coupled thermal-flow simulation.

  - Linearization and convergence
    The flow solver uses linearization and convergence to solve for pressure, velocity, enthalpy, and other variables. It is important to understand the time versus non-linear convergence loops, and the equations that are solved.

Flow solver flowcharts

This section consists of flowcharts that illustrate the methodology of the flow solver when you run a simple steady-state or transient simulation, and does not cover all features and situations. It also highlights how the flow solver is coupled to the thermal solver for a simple steady-state or transient coupled thermal-flow simulation.

A wide range of situations and features have been omitted for simplicity. They include but are not limited to active and passive scalars, disjoint mesh paring, and immersed boundary methods.

In the flowcharts:

ϕ(t) is the value of the unknown variables—pressure, velocity, and enthalpy—at time t.
ϕⁿ is the value of the unknown variables at the non-linear iteration n.
n_max is the maximum number of convergence iterations.
t_max is the final simulation time for a transient simulation.
