Recoil pressure in laser welding

Krishna Thombare · October 7, 2023, 07:37

I am trying to simulate the effect of recoil pressure on meltpool in laser welding. I want to include it as body force, but formula I have is in scalar form , I have heard that to convert it into body force we can multiply by gradients . I am trying the formula attachedScreenshot from 2023-10-07 17-05-04.png . In this eqn 17 I am not sure what I denotes??
If anyone have anyother ways or knows about this Please help??
