Hi I am working on laser cutting process. I know that we can able to kill the element by dropping young’s modulus (close to zero) method using comsol. However, I would like to kill the elements throughout the plate thickness. Therefore, I should give more numbers of laser passes on the material to make through cut. So, I need to apply the moving heat source on live element in the next laser pass. I do not have much idea on the selection of next layer of element after removed the top surface element. Is it possible to select the next layer of elements after killing the elements of the top surface?
