dflux

Dear Mechanicians,

time and again the question of modeling moving heat sources pops up, often in the context of laser heating.

One can achieve this using the subroutine DFLUX in ABAQUS.

I decided to post some links here to avoid responding with a longer explanation to every individual seeking assistance.

Please note that I have never worked with any one of these codes and have no access to ABAQUS at present.

No warranty is given by me.

Hi Every one, 

I noticed one thing about specifying surface flux in abaqus/cae.  I specify user-defined surface flux in abaqus/cae, but the inp-file  writes *DsFlux as seen in the following lines,

** LOADS
**
** Name: Load-1   Type: Surface heat flux
*Dsflux
_PickedSurf28, SNU, 10.

When I submit the Job, I see this error

Error in job Essai: USER SUBROUTINE DFLUX IS MISSING
Job Essai: ABAQUS/Standard aborted due to errors. 

Can one help me
