Gas metal arc welding simulation using LS-DYNA

Hallo,

I am working on gas metal arc welding simulation and i am trying to compute the temperature field by using the commerical software LS-DYNA. I am totally new to this software thats why i am facing lot of hurdle in the simulation.

Can anyone here tell e how i can use the LS PrePost Welding GUI and make me heat source move along the weld line?? It will be very helpful, if anyone can send me some detail documents regarding such kind of simulation.

Regards

Braj
