RampCFL

RampCFL#

class RampCFL[source]#

Bases: Flow360BaseModel

RampCFL class for the Ramp CFL setting of time stepping.

Example

>>> fl.RampCFL(initial=1, final=200, ramp_steps=200)

Attributes

initial: float, optional#

Initial CFL for solving pseudo time step. In steady simulations default value is 5. In unsteady simulations default value is 1.

Default:

None

final: float, optional#

Default:

None

ramp_steps: int, optional#

Number of pseudo steps before reaching RampCFL.final within 1 physical step. In steady simulations default value is 40. In unsteady simulations default value is 30.

Default:

None
