zone mechanical
command
Syntax
- zone mechanical keyword
Primary keywords:
Set parameters for a static mechanical analysis that are specific to zones. The following keywords apply.
- active b
Set mechanical calculation
off
/on
(default ison
). The mechanical calculation may be turned off for a thermal-only calculation or a fluid flow-only calculation. Note that in general it is preferable to set mechanical calculations off for the entire model with themodel mechanical active
command.
- damping keyword <range>
Select the damping type for the static, mechanical process (the default damping is
local
).- combined <f >
Combined local damping (default is 0.8).
- local <f ><alternate>
Local damping (default is 0.59). If the
alternate
keyword is specified, an experimental alternate implementation of local damping is used that produces less sensitivity to small changes in the model.
- energy keyword
Allow elastic strain energy and dissipated plastic energy to be calculated (see Energy Calculation in FLAC3D).
- active b
Turn the calculations
off
/on
in the stress-strain loop.
- clear <range>
Set the four zone energy values in every zone back to zero. The
zone mechanical active
command does not clear these values. This stops accumulating plastic work over any desired interval, and resumes accumulating at any time from where it left off.
- list
Show a summary of current zone mechanical settings in the console.
- safety-factor f
Set a safety factor applied to the gridpoint stiffness calculation, which is done in stability calculations for both static and dynamic mode. The default safety factor is 1.0.
