ABAQUS Keywords Reference Manual  

*CFLOW
Specify concentrated fluid flow.

This option is used to apply concentrated fluid flow to any node in consolidation problems.

Product: ABAQUS/Standard  

Type: History data

Level: Step  

References:

Optional parameters:

AMPLITUDE

Set this parameter equal to the name of the amplitude curve that defines the magnitude of the flow during the step. If this parameter is omitted, 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 “Procedures: overview,” Section 6.1.1 of the ABAQUS Analysis User's Manual).

OP

Set OP=MOD (default) for existing *CFLOWs to remain, with this option modifying existing concentrated flows or defining additional concentrated flows.

Set OP=NEW if all existing *CFLOWs applied to the model should be removed.

Data lines to define concentrated flow: 

First line:

  1. Node number or node set label.

  2. (Not used.)

  3. Reference concentrated flow magnitude.

Repeat this data line as often as necessary to define concentrated flows.
