model thermal command
Syntax
- model thermal keyword
-
This command sets parameters for a thermal material analysis (only available if
model configure thermal
has been specified. [cs: Common trouble] See the topic ref-thermalanalysis-.- active b
The thermal process is on, by default, when the
model configure thermal
command is given. Specify active off to suppress thermal calculations.
- list
Display thermal calculation-mode information.
- slave b
Specifies that thermal mode is to be considered a slave, and cycled to equilibrium after each master step has been taken. This particular option is provided for completeness, but is rarely useful in thermal calculations.
- substep i
Specifies the maximum number of steps the thermal process will take when solving with slave on.
- time-total f
f is the accumulated thermal time for the model. This can be reset to any value, and will continue to be accumulated during cycling after that.
- 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.
- safety-factor f
Set the timestep safety factor, or the factor that is multiplied by the stable timestep calculated when auto mode. By default, f = 0.8.
- update i
This value is not used in FLAC3D thermal timestep calculations.
