This option is used to apply distributed surface fluxes in fully coupled thermal-stress analysis. In ABAQUS/Standard it is also used for heat transfer and coupled thermal-electrical analyses.
Products: ABAQUS/Standard ABAQUS/Explicit
Type: History data
Level: Step
Set this parameter equal to the name of the amplitude curve that defines the magnitude of the distributed fluxes during the step (Amplitude curves, Section 19.1.2 of the ABAQUS Analysis User's Manual).
If this parameter is omitted for uniform flux types in an ABAQUS/Standard analysis, 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 (Procedures: overview, Section 6.1.1 of the ABAQUS Analysis User's Manual). If this parameter is omitted in an ABAQUS/Explicit analysis, the reference magnitude is applied immediately at the beginning of the step.
For nonuniform flux type SNU (which is available only in ABAQUS/Standard), the flux magnitude is defined in user subroutine DFLUX, and AMPLITUDE references are ignored.
First line:
Surface name.
Distributed flux type label S or SNU.
Reference flux magnitude (units JT1L2). This value is needed for uniform fluxes only. If it is given for nonuniform fluxes, it will be passed into user subroutine DFLUX, where the actual flux magnitude is defined.
Repeat this data line as often as necessary to define distributed fluxes for different surfaces.
