model fluid command
Syntax
- model fluid keyword
-
Set parameters for a fluid flow analysis. This command is only available
model configure fluid
has been specified. See the ref:-Fluid-Mechanical Interaction <fluid-mechanical>- section for complete information. :flag3:[cs: commmon]`- active b
The fluid process is on, by default, when the
model configure fluid
command is given. Specify active off to suppress fluid calculations.
- list
Display fluid calculation-mode information.
- time-total f
f is the accumulated fluid time for the model. This can be reset to any value, and will continue to be accumulated during cycling after that.
- slave b
Specify that fluid mode is to be considered a slave, and cycled to equilibrium after each master step has been taken.
- substep i
Specify the maximum number of steps the fluid process will take when solving with slave on.
- timestep
- automatic
The stable timestep is calculated automatically. This is the default setting.
- fix f
Set the timestep to be the fixed value f. All timestep calculations are skipped. Setting a value greater than the calculated critical timestep will result in an error.
- increment f
Set the incremental amount that the timestep is allowed to increase from one cycle to the next in auto mode. By default, f = 1.05. The timestep can decrease by any amount to ensure stability.
- maximum f
Set the maximum allowed timestep. By default, there is no bound to the maximum timestep.
