HI EVERYBODY,

I HAVE BEEN TRYING TO DO THE THERMAL ANALYSIS OF WELDS COUPLED WITH THE MECHANICAL ANALYSIS TO DETERMINE THE RESIDUAL STRESSES RESULTING IN IT.I HAVE COUPLE OF DOUBTS IN THIS CONCERN-

1.THERE IS THE USE OF FILLER MATERIAL-I KNOW ELEMENT DEATH AND BIRTH METHOD IS TO BE USED BEHIND IT,BUT DONT KNOW HOW TO APPLY IT

2.SECONDLY THE MOVING HEAT SOURCE-WHETHER ANY GAUSSIAN DISTRIBUTION IS TO APPLIED AND HOW TO GET A MOVING HEAT SOURCE.

3.WHETHER  ALL CONVECTIVE AND RADIATIVE BOUNDARY CONDITIONS HAVE TO BE APPLIED ON OTHER SURFACES SIMULTANEOUSLY.

IT WOULD BE OF GREAT HELP IF SOME BODY THROWS SOME LIGHT IN THIS SITUATION,ANY POSSIBLE SOLUTIONS AND A APDL FILE TO MY MAIL ID WOULD BE GREAT..
