# BODY HEAT FLUX ABAQUS

In Abaqus, how to define multi heat flux by using DFLUX? | Q&A
In Abaqus, how to define multi heat flux by using DFLUX? I'm trying to define two different heat flux in my model, one is body heat generation, the other one is surface heat flux flow out of the
Defining a body heat flux - abaqus-docs
In the Magnitude text field, enter the body heat flux magnitude (units JT −1 L −3). A positive magnitude indicates heat flow into the body. If desired, click the arrow to the right of the Amplitude field, and select the amplitude of your choice from the list that appears. Alternatively, you can click to
Abaqus Users - Volumetric and surface heat flux
Hello, What is the difference between volumetric and surface heat source in Abaqus? When volumetric heat source is applied either surface integral modifies itself converting “q” W/m2 into W/m3 using a keyword *Dflux and volume integral eliminates or its vice-versa? Whether “r” is the heat flux per unit volume generated within the body or heat supplied externally into the body?

Body Heat Flux in Abaqus Simulia : AskEngineers
I've recently started using Abaqus for some thermo-mechanical problems. I am using SI (kg,m,s) units for my model. My query is: What is the unit of "body heat flux" in SI units? I know that heat flux is expressed in W/m2 (Watt/sq metre) in SI units. But what about body heat flux? Will it be W/m3 (Watt/cubic metre)?
30.2.1 Thermal contact properties
ABAQUS maintains the radiative heat flux even when the surfaces are in contact. This causes only a minor inaccuracy since normally the heat flux from conduction is much larger than the radiative heat flux. ABAQUS defines the heat flow per unit surface area between corresponding points as
*DFLUX - MIT
For flux entering the body the magnitude of the flux is positive, for flux leaving the body it is negative. If the flux is nonuniform the label takes the form SxNUy and a user subroutine dflux.f must be provided specifying the value of the flux. The label can be up to 20 characters long.
