Thermal analysis - travelling heat loads

Hi,

I’m Sharan Hallur.

We are exploring Creo Simulate thermal analysis & I have queries regarding travelling heat loads in the training material.  .

1. In the heat load dialogue box {applying heat load to the weld}, please help me in understanding the time function 1:  exp(-1*(((s-time)/50)^2)),what is its significance & how you arrived to it!

2. I tried to add multiple welds in the same weldment, but all welds are simultaneously starting. How to make the heat loads run one after the other?

Really appreciate your help!

Thanks

Sharan Hallur
