moving heat source on fluent
 

Hello,

Can fluent modeling a moving heat source on a surface using UDF fonction and how?.The heat source is a moving laser spot heating a solide surface. and I would like to watch the transient nature of the surrounding temperature profiles. Please help me. thanks to all

Re: moving heat source on fluent
 

YOU CAN HAVE A MOVING SOURCE. FIRST OF ALL, TO CREATE A SOURCE YOU MUST ADAPT A REGION AND THEN CREATE A SEPARATE CELL ZONE.(UNTIL HERE I HOPE YOU AGREE). THIS CELL ZONE IN 2-D HAS 2 INTERIORS ONE IS THE OUTLINE AND THE OTHER THE CELLS INSIDE. YOU IMPOSE YOUR CONDITIONS TO BOTH (DYNAMIC MESH ZONES IN DYNAMIC MESH PARAMETERS).YOU HAVE TO MAKE A C++ FILE DESCRIBING THE MOTION OF THESE ZONES WITH THE CLASSIC COMPILING PROCEDURE.

thanks STK
 

thank you very much STK.CAN I GET YOUR MAIL? I HAVE DONE A SIMPLE MODEL TO SHOW YOU THE PROBLEM I AM MODELING.I AM A NEW USER OF FLUENT 6.1.22 AND I HAVE READ THE TUTORIAL OF GAMBIT AND FLUENT BUT I HAVE NOT A SOLUTION .

I am doing my project work in ansys fluent weld pool simulation.Could you please provide me with a udf for simulating a moving heat source in fluent.
