  My question is about the code for the heat and mass source code of two parameters' values for the powder system deposition for directed energy deposition, and I just need help to understand these two values because I saw the impact of these two values. One value is associated with the heat source parameters, which is 0.1, and the other value is related to the mass source parameters, which is 6.0. What is the perfect name for those values? Should I call them that? Is there anyone who can kindly help me understand this? The information will be a tremendous help for me. I have already provided all the details, including the image, equations, code, and parameter values indicated by the red circle.
