zone gridpoint initialize
command
Syntax
- zone gridpoint initialize keyword <range>
Primary keywords:
displacement displacement-x displacement-y displacement-z displacement-small displacement-small-x displacement-small-y displacement-small-z extra force-applied force-applied-x force-applied-y force-applied-z head multiplier position position-x position-y position-z pore-pressure ratio-target saturation temperature velocity velocity-x velocity-y velocity-z
Assign or initialize values to all gridpoints in the range. Keywords available can be chosen from the following list:
- displacement v <[gridpointinitializeblock]>
Gridpoint displacement.
- displacement-x f <[gridpointinitializeblock]>
Gridpoint displacement in the \(x\)-direction.
- displacement-y f <[gridpointinitializeblock]>
Gridpoint displacement in the \(y\)-direction.
- displacement-z f <[gridpointinitializeblock]>(3D ONLY)
Gridpoint displacement in the \(z\)-direction.
- displacement-small v <[gridpointinitializeblock]>
Accumulated small-strain displacement at a gridpoint (used in interface calculations).
- displacement-small-x f <[gridpointinitializeblock]>
Accumulated small-strain \(x\)-displacement at a gridpoint (used in interface calculations).
- displacement-small-y f <[gridpointinitializeblock]>
Accumulated small-strain \(y\)-displacement at a gridpoint (used in interface calculations).
- displacement-small-z f <[gridpointinitializeblock]>(3D ONLY)
Accumulated small-strain \(z\)-displacement at a gridpoint (used in interface calculations).
- extra i a<[gridpointinitializeblock]>
Extra grid variable for extra array index i and a. [CS: this seems like a pretty thin description; previously was flagged for that reason]
- force-applied v <[gridpointinitializeblock]>
The total applied force at a gridpoint. This includes all sources, including forces due to gravity.
- force-applied-x f <[gridpointinitializeblock]>
The total applied force in the \(x\) direction at a gridpoint. This includes all sources, including forces due to gravity.
- force-applied-y f <[gridpointinitializeblock]>
The total applied force in the \(y\) direction at a gridpoint. This includes all sources, including forces due to gravity.
- force-applied-z f <[gridpointinitializeblock]>(3D ONLY)
The total applied force in the \(z\) direction at a gridpoint. This includes all sources, including forces due to gravity.
- head f <[gridpointinitializeblock]>
This is a synonym for the
zone gridpoint pore-pressure head
command. Please see that command for documentation details
- multiplier f <[gridpointinitializeblock]>
Integer multiplier of the gridpoint used in dynamic multi-stepping.
- position v <[gridpointinitializeblock]>
Position of a gridpoint.
- position-x f <[gridpointinitializeblock]>
\(x\)-coordinate of gridpoint
- position-y f <[gridpointinitializeblock]>
\(y\)-coordinate of gridpoint
- position-z f <[gridpointinitializeblock]>(3D ONLY)
\(z\)-coordinate of gridpoint
- pore-pressure f <[gridpointinitializeblock]>
This is a synonym for the
zone gridpoint pore-pressure initialize
command. Please see that command for documentation details.
- ratio-target f <[gridpointinitializeblock]>
Specifies the target local force ratio that is considered to be converged for mechanical calculations. The default value is 1e-4. A local force ratio of this value will result in a convergence value of 1.0 for the gridpoint. See the convergence keyword in the
model solve
command.
- saturation f <[gridpointinitializeblock]>
Saturation at the gridpoint. Only available if the
model configure fluid-flow
has been given.
- temperature f <[gridpointinitializeblock]>
temperature at the gridpoint. Only available if the
model configure thermal
has been given.
- velocity v <[gridpointinitializeblock]>
Velocity of a gridpoint.
- velocity-x f <[gridpointinitializeblock]>
\(x\)-velocity of gridpoint
- velocity-y f <[gridpointinitializeblock]>
\(y\)-velocity of gridpoint
- velocity-z f <[gridpointinitializeblock]>(3D ONLY)
\(z\)-velocity of gridpoint

Keyword Block
The following keywords may be used to modify a supplied value. If the description of the modifier keyword mentions what type of value it may be applied to (e.g. scalar value, vector value, etc.), be sure there is a match between the modifier and the main keyword value. The commands main keywords are: displacement
, displacement-small
, displacement-small-x
, displacement-small-y
, displacement-small-z
, displacement-x
, displacement-y
, displacement-z
, extra
, force-applied
, force-applied-x
, force-applied-y
, force-applied-z
, head
, multiplier
, pore-pressure
, position
, position-x
, position-y
, position-z
, ratio-target
, saturation
, temperature
, velocity
, velocity-x
, velocity-y
and velocity-z
.
- gradient v <origin v >
Apply a gradient to the scalar-value provided. Note the
origin
keyword is optional, however, the default value (0,0,0) is used if theorigin
keyword is not included in the command — which may not produce the intended result.
- local
Specify that the value supplied for the keyword is in the local coordinate system of the gridpoint (if any). By default values are initialize in the global system.
This keyword cannot be used with the following keywords of the zone gridpoint initialize command: extra.
- vary v
Apply a linear variation to the scalar-value provided.
