Abaqus/CAELoad module
Optional parameters
- AMPLITUDE
-
Set this parameter equal to the name of the
AMPLITUDE curve that defines the magnitude of the seepage flow
during the step. If this parameter is omitted for uniform seepage types, the
reference magnitude is applied immediately at the beginning of the step or
linearly over the step, depending on the value assigned to the AMPLITUDE parameter on the
STEP option (see
Defining an analysis).
Amplitude references are ignored for flows defined in user subroutine
DFLOW.
- OP
-
Set OP=MOD (default) for existing
DFLOWs to remain, with this option modifying existing flows or
defining additional flows.
Set OP=NEW if all existing
DFLOWs applied to the model should be removed. New flows can be
defined.
Data lines to define
uniform seepage
- First
line
-
Element number or element set label.
-
Distributed seepage type label (see
About the element library).
-
Reference seepage magnitude. (Units of LT−1.) The
seepage magnitude is the pore fluid effective velocity crossing the surface at
this point in an outward direction.
Repeat this data line as
often as necessary to define uniform seepage for various elements or element
sets.
Data lines to define
nonuniform seepage
- First
line
-
Element number or element set label.
-
Distributed seepage type label (see
About the element library).
-
Seepage magnitude (optional). If given, this value is passed into user
subroutine
DFLOW in the variable used to define the seepage magnitude.
Nonuniform seepage magnitudes are defined via user subroutine
DFLOW.
Repeat this data line as often as necessary to define
nonuniform seepage for various elements or element
sets.
